Hi there

The demo file works pretty well, but on real data the words appear clumpsed. Not I tried to reduce font size (down to 0.00001) and all the words appear but on the same size

Thank you very much in advance for any help

Cheers!

When I install wordcloud2 using CRAN I get version 0.2.1:

> install.packages("wordcloud2")
> library(wordcloud2)
> sessionInfo()
...
other attached packages:
[1] wordcloud2_0.2.1

However, when I try to install the latest version from github, I get version 0.2.0:

> library(devtools)
> install_github("Lchiffon/wordcloud2")
> library(wordcloud2)
> sessionInfo()
...
other attached packages:
[1] wordcloud2_0.2.0

Why do I get a lower version number when installing via github?

Is it possible to customize the hover text?

I have a dataset with 3-4 very large words compared to all the others, to solve this I want to take the log of the frequencies (technically I'm taking the ceiling of the log base 2 and then adding 1). I'd either like to customize what frequency is shown in the hover text (or just not show it at all. Is that possible?

Example http://data.dyumnin.com/analysis/tweeplytics/ashutosh83B.html
This page has 4 wordclouds, If we mouse over the words on any of the wordclouds the rectangular frame and word count appears over the first cloud instead of the cloud over which the mouse is positioned.

Hello,
The function "wordcloud2(demoFreq, figPath = figPath, size = XXX, color = XXX)" doesn't work after updating Mac OS, R and RStudio.

there is a link as follows:
http://www.ooopic.com/sheying/51040521.html

would you please give an example？

另外，我发现通过figPath指定自定义图形时有时候达不到预期效果，比如只填充了图片的轮廓（空心），或者图片的不规则形状被平滑（如带有不规则边缘的云朵输出后成为椭圆），不知道在图片选取上有什么技巧或注意事项？

After upgrading to version 0.2.1 I get an error message that variable iii can't be found in my Shiny apps that uses wordcloud2. The word cloud is rendered, but other parts of the app breaks. Downgrading to 0.2.0 solves the issue. The culprit seems to be the function call that was removed from wordcloud2.R 1696d2f. Will a new version be published to CRAN without this bug?

I believe this is the same issue as experienced here and related to this

Each time I create a word cloud the words appear in a different order. Running set.seed prior does nothing. Is there a way to make it consistent?

Is it possible to return a click on a word of the wordcloud as a click event in shiny in order to bind other objects (e.g. bsModal) to it? For example, in plotly this is a accomplished by generating an object that can be accessed from within the shiny session and holds the event data (e.g. click coordinates) (https://plot.ly/r/shinyapp-linked-click/).

Hello..
is there any way to disable small word inside big Character ?

Is it possible to use render the letter based wordcloud (letterCloud) in Shiny with renderWordcloud2.R ?Thanks :-)

First of all congratulations to bring wordcloud to the R community.

I'm using wordcloud2 with this code in shiny:

**output$plot <- renderWordcloud2({

    wordcloud2(data.frame(words()$word, words()$frequencia),
               color = rep(c("#17882c","#EC644B",
                             "#4B77BE","#FDE3A7",
                             "#C8F7C5","#913D88",
                             "#D2527F","#336E7B",
                             "#E9D460","#D35400",
                             "#1BA39C","#9B2335"),
                           length.out=nrow(data.frame(words()$word, words()$frequencia)))) + WCtheme(1)       
    
  })**

However i'm receiving this error message:

WCtheme: could not find function "WCtheme"

If a remove WCtheme everything works well, but with characeter enconding errors.

Before i was able to run this example without any errors.

Best regards!

Hi,

Please have a look at using a tibble, cf. as_data_frame(), instead of a standard R data frame for the input data. The result is all the same, but it think it would be nice if the warning message could be dropped when using a tibble.

And thanks for the lovely package!

现在出现了这个问题，letterCloud(demoFreqC,word="R",size = 1) 出来之后没有颜色，只有形状没有颜色，如下图，是怎么回事？

I tried to save the widget with the self-contained option, that does not work.
There is nothing fancy in the frequency table I use, normal English words. Would be great if you could fix it. (Where I would like to use the widget, there is no option for using the non self-contained form of it.)

hello, i study on Text mining and i do not know how can i create number wordcloud2. I know shape of star or peace. But i can not number 10 as shape of wordcloud. Can you help me?

wordcloud2::wordcloud2(asd,word="R", color='random-light' , backgroundColor="black") it is okey. but
wordcloud2::wordcloud2(asd,figPath="10.png", color='random-light' , backgroundColor="black") does not work.

hello
when i want to plot two wordcloud on the same page only the first one is showing

i put ther description on stackoverflow https://stackoverflow.com/questions/54943338/two-wordcloud2-on-the-same-shiny-page/54949680?noredirect=1#comment96732005_54949680

the simple script

library(wordcloud2)
library(shiny)

ui <- fluidPage(
    wordcloud2Output('wordcloud2'),
    wordcloud2Output('wordcloud3')
)

server <- function(input, output) {
    output$wordcloud2 <- renderWordcloud2({
            wordcloud2(demoFreq)
    })

    output$wordcloud3 <- renderWordcloud2({
            wordcloud2(demoFreq)
    })
}

shinyApp(ui = ui, server = server)`

when i check the html only the first one have "visibility: inherit"

WordCloud2 is a fancy job, but I wonder if it could be displayed right in a jupyter notebook.
I tried a simple way but failed.

library(wordcloud2)
wordcloud2(demoFreq)

HTML widgets cannot be represented in plain text (need html)

I am using a wordcloud2 in an rmarkdown html_document. When I include multiple wordclouds the first one works fine but subsequent ones don't display. I can get around this by using saveWidget and webshot to include a png of the wordcloud, but this is not ideal (I like being able to hover over the wordcloud and see the counts). Do you have a solution for this?

Thank you!

I'm trying to use wordcloud2 to generate a picture like this:

But it's too small. Could you help me to make this image larger?
Here is my code:
library(wordcloud2)
library(htmlwidgets)
library(webshot)
filepath = "C:\Users\zjkgf\PycharmProjects\ipfenxi\picture1.txt"
s = read.csv(filepath, fileEncoding = "utf-8")
so = demoFreq
st = wordcloud2(s,minSize=2, color = 'random-dark', backgroundColor = "white",fontFamily = "微软雅黑", shape = 'square')

Hello,
I'm enjoying wordcloud2 and hoping to make use of the unique features.
However, the png mask and letterCloud functions have been silently failing.
Also, using the provided example of setting figPath to a png fails as per https://rstudio-pubs-static.s3.amazonaws.com/187645_426d719fae56457f84d767fd6f076a43.html:

figPath = system.file("examples/t.png",package = "wordcloud2")
wordcloud2(demoFreq, figPath = figPath, size = 1.5,color = "skyblue")

Similarly, the "https://www.r-bloggers.com/the-wordcloud2-library/" Peace symbol example command: wordcloud2(demoFreq, figPath = "peace.png", size = 1.5, color = "skyblue", backgroundColor="black")
also silently fails.

I have Rstudio v. 1.2.747 on Windows 10

From : https://www.r-graph-gallery.com/196-the-wordcloud2-library/
I tried the following code chunk without success, Ok for html but png is a white file...
`

install webshot

library(webshot)
webshot::install_phantomjs()

Make the graph

my_graph=letterCloud(demoFreq,"@",1)

save it in htmllibrary("htmlwidgets")

saveWidget(my_graph,"tmp.html",selfcontained = F)

and in png

webshot("tmp.html","fig_1.png", delay =5, vwidth = 480, vheight=480)
`

Thank you very much for your help !

Hello..
when i am generating wordcloud then i get many small word inside big font .

So is there any way to small word not fill inside big font ?

Thanks

Thank for your impressive work,

Do you know if there is any possibility to nicely save the cloud in png or svg format? Being able to change the resolution and such would be really nice :)

Cheers

The description text of the minSize parameter says "A character string of the subtitle".
I believe this should be an error.
In wordcloud2.js, it is described as "minimum font size to draw on the canvas."
And also, we may also need to add another space to the text, so that it will be a sub-item.

The cran version gives an error if webshot is not available:

    Error: processing vignette 'intro.Rmd' failed with diagnostics:
    there is no package called 'webshot'
    Execution halted 

Would it be possible to release a new version to CRAN?

I used "wordcloud2 version 0.2.1"&"R 3.5.0".
When I tried the demo,
letterCloud(demoFreq,"R")
It couldn't show the output normally , but only a black "R" instead.
How could I deal with the problem?

It's been a few months now and lettercloud still doesn't work. Any updates on this?

Hi, hope this message finds you well.
I tried to install and run wordcloud2 on Jupyter Notebook, however, it didn't show the results but a small white rectangle. Would you please check it out?
Thank you!

The most recent merged PR from @JacobXPX seems to have issues with hover info and issues with click events when rendering multiple wordcloud2s. I have not yet had time to look into what causes the issue, but I know the issues weren't present in my initial PR (based on the example apps shown below).

Please let me know if these issues are not reproducible or if they are due to user error. If these are consistent issues then I think they should be resolved before the next push to CRAN.

All example output below are from running the github version of wordcloud2 in Chrome.

Issues with multiple wordcloud2s:

• No hover info displayed
• Clicking a word in either wordcloud2 updates both input clicked words

devtools::install_github('Lchiffon/wordcloud2')

library(shiny)
library(wordcloud2)
shinyApp(
  ui=shinyUI(fluidPage(
    #using default clicked word input id
    wordcloud2Output("my_wc"),
    #using custom clicked word input id
    wordcloud2Output("my_wc2", clickedWordInputId = "wc2_clicked_word"),
    
    verbatimTextOutput("print"),
    verbatimTextOutput("print2")
  )),
  server=shinyServer(function(input,output,session){
    output$my_wc  = renderWordcloud2(wordcloud2(demoFreq))
    output$my_wc2 = renderWordcloud2(wordcloud2(demoFreq))
    
    #using default clicked word input id
    output$print  = renderPrint(input$selected_word)
    #using custom clicked word input id
    output$print2 = renderPrint(input$wc2_clicked_word)
  })
)

Issues with single wordcloud2

• Hover info is displayed incorrectly at bottom left corner of the wordcloud2 html widget

devtools::install_github('Lchiffon/wordcloud2')

library(shiny)
library(wordcloud2)
shinyApp(
  ui=shinyUI(fluidPage(
    #using default clicked word input id
    wordcloud2Output("my_wc"),
    
    verbatimTextOutput("print")
  )),
  server=shinyServer(function(input,output,session){
    output$my_wc  = renderWordcloud2(wordcloud2(demoFreq))

    #using default clicked word input id
    output$print  = renderPrint(input$selected_word)
  })
)

I have tried many parameter of minRotation, maxRotation with and without rotateRatio but can not achieve words ratation as per attach sample from https://www.jasondavies.com/wordcloud/ online wordcloud generator. How this rotation can be achieved?

Hi, I really like the clouds generated by wordcloud2 and I am trying to use the click functionality in shiny on Firefox but cannot get it to work. My minimal code is pasted below. Nothing happens when I click on a word. I am using the github master branch as the CRAN package does not seem to have this functionality yet (?). Thanks!

shinyApp(
    ui=fluidPage(
        wordcloud2Output("wc"),
        textOutput("text")
    ),
    server=function(input, output, session){
        click <- 0
        output$wc <- renderWordcloud2({
            wordcloud2(
                data.frame( word=c("one","two"), freq=c(1,2) )
            )
        })
        output$text <- renderPrint({
            print( paste( click, input$wc_clicked_word ) )
            click <- click + 1
        })
    }
)

I have created a nice word cloud with wordcloud2 but the exported png file has a bad resolution when I print it (on a big A3 sheet) - same when I zoom in a bit too much on the screen.
To save the output as an image, I used the "Export/save as image" in the Rstudio viewer.
I also tried via saveWidget (save as html) and webshot (convert html to png) but the resolution is also low.
I have tried with grDevices::png or grDevices::tiff, where you can control for the resolution, but I get a blank image (works with wordcloud but not wordcloud2).
Is there another possibility I should try?

Thanks for your package, it's very useful.

I met an issue when using htmlwidgets::saveWidget. Could you help on that?

library(wordcloud2)
xx <- wordcloud2(data = demoFreq)
htmlwidgets::saveWidget(widget = xx, file = "test.html", selfcontained = TRUE)

When opening the file test.html, nothing is displayed. An javascript error can be read in the js console: Uncaught TypeError: canvas.getBoundingClientRect is not a function(…)

Thanks for awesome work. Kindly guide me how can generated wordcloud can be export as vector. I have already created PDF file using saveWidget and webshot code but PDF contain raster image not vector.

If vector export from html5 canvas is not possible than how can I render high resolution wordcloud. Increasing size parameter is also not helpful as wordcloud is only visible in shown browser page. I have also tried to export from RStudio but image dimension can be set maximum to 1200 pixles. I need wordcloud in size atleast of 2500pxx2500px

I created a simple example before to demonstrate an issue with hover info in previous versions (#18). This example no longer works in the newest version on CRAN. When I run this only one of the 4 wordclouds is plotted in the shiny app.

I have not yet had time to investigate what's causing the issue

Small reproducible example.

library(shiny)
library(wordcloud2)
shinyApp(
  ui=shinyUI(fluidPage(
    fluidRow(
      column(width=6,align="center", wordcloud2Output("my_wc")),
      column(width=6,align="center", wordcloud2Output("my_wc2"))
    ),
    wordcloud2Output("my_wc3"),
    wordcloud2Output("my_wc4")
  )),
  server=shinyServer(function(input,output,session){
    output$my_wc  = renderWordcloud2(wordcloud2(demoFreq))
    output$my_wc2 = renderWordcloud2(wordcloud2(demoFreq))
    output$my_wc3 = renderWordcloud2(wordcloud2(demoFreq))
    output$my_wc4 = renderWordcloud2(wordcloud2(demoFreq))
  })
)

I'm developing a shinydashboard app, the problem I'm having is the wordcloud is shown while it's being created.
Then I change tabs, get back to the shiny app and the Wordcloud is gone!
However as I hove over the wordcloud (hidden now) I see the hover values.
I've tried using the 0.2.0 version but this still didn't work. Any ideas?

I have texts in UTF-8, but it seems that your package doesn't "see" other characters than latin:

docs <- c("текст один", "текст два")
docs <- enc2utf8(docs)
corp <- VCorpus(VectorSource(docs))
tdm <- TermDocumentMatrix(corp)
m = as.matrix(tdm)
wordcloud2(data = m, gridSize=15, ellipticity=2)

郎老师，在统计之都上看见你关于wordcloud2包的介绍，试着用letterCloud做了一下，数据代码都是用的你网页上的那个，结果出现这个错误，能否帮我解答下？谢谢。

Hi, can you make it so that the program shows warnings (or other ways to let me know) when it can't plot certain words because of lack of space? I'm making a wordcloud of hundreds of usernames and want to make sure none of them is missing.

已经解决了，感谢！是环境变量的问题

@Lchiffon I understand that you can specify either a single angle or a range of angles.
Is there a way to specify a pair of angles: words to either appear horizontally and vertically (0, 90 or pi/2)? I tried to play around with the following parameters, but could not achieve the result I am expecting.

wordcloud2(wc, minSize=2, color="random-light",
		    fontFamily="Helvetica", fontWeight="normal",
		    minRotation=0, maxRotation=0, rotateRatio=1,
		    # minRotation=pi/6, maxRotation=pi/6, rotateRatio=1,
		    shape="rectangle")

See zzz.R. This can have really bad side effects for the user and other packages.

Nice package by the way :)

Hi,

This might be a really stupid question...
I thought the hover effect exists by default, however, the plot I get on both Viewer in RStudio and shiny are completely static... I tried with the most basic example "demoFreq", but I can't see anything interactive. What am I missing...?

Thanks!!!

Hi, lchiffon
when i tried to download wordcloud2, matters following questions happened,why?

library(devtools)

Downloading GitHub repo lchiffon/wordcloud2@master
Error in untar2(tarfile, files, list, exdir) : incomplete block on fil

Hello,

I use your package wordcloud2 to display several word clouds on my data.

I understand that we always need to specify the size argument of the wordcloud2 function otherwise we have a risk that all the words (the biggest words) are not published, depending on the size of the output viewer (cf. closed issue "Lettercloud skips words" #16).

Is there a way to avoid setting the size for each plot ? I want to use this in a Shiny app with several word clouds (and sometimes huge differences between the frequencies of words) so I'm looking for a general way and ideally that the user does not have to change ?

I can add an exemple if my question is not clear.

Regards,
Jean-Louis

Hi Dawei,

When I use wordcloud2 to plot some words, for instance, "approximately" and "impairment" can't be plotted in the Rstudio. I guess this is a small problem, because I find the wordcould could complete this job.
Thanks millions, Dawei. And I love your wordcloud2, it's a fancy package.

When I use letterCloud, it doesn't display all the high frequency words. The longer words I try to spell in letterCloud, the more words are missing. I notice that it is the same in the vignette https://cran.r-project.org/web/packages/wordcloud2/vignettes/wordcloud.html. The letterCloud for "R" doesn't display "Oil" and "Said" that appears to be the words with highest frequencies (displayed in the wordclouds above). The same for the "WORDCLOUD2" example in the vignette.
