recharts-1's Introduction

recharts

This is a prototype of porting ECharts into R using htmlwidgets. I only spent a few days on it last year, and I hope more R users can contribute to it. To install this package (please use R >= 3.2.0):

install.packages(
  'recharts',
  repos = c('http://yihui.name/xran', 'http://cran.rstudio.com')
)

Some "hello world" examples:

library(recharts)
echart(iris, ~Sepal.Length, ~Sepal.Width)
echart(iris, ~Sepal.Length, ~Sepal.Width, series = ~Species)
# bar chart
bar_df = data.frame(
  date = rep(paste("day",1:10), 2),
  temperature = floor(rnorm(n = 20, mean = 20, sd = 10)),
  location = rep(c("NY","DC"), each = 10)
 )
echart(bar_df, ~date, ~temperature, ~location)
# line chart
echart(bar_df, ~date, ~temperature, ~location, type="line")
# histogram
echart_hist(rnorm(1000))

See the package vignette for more information if you want to contribute:

vignette('design', package = 'recharts')

See https://github.com/taiyun/recharts for a similar project that we worked on before. Without the blessings of htmlwidgets, it is much more difficult to maintain that project. I hope this one can grow into a truly nice and exciting package.
