adjustedcranlogs's Introduction

adjustedcranlogs

CRAN_Status_Badge

Overview

adjustedcranlogs is a wrapper around the cranlogs package that removes CRAN-wide shared daily downloads and re-download/CRAN mirror spikes due to package updates.

Installation

# To install: 
install.packages("adjustedcranlogs")

# To install developmental version:
# install.packages("devtools")
devtools::install_github("tylermorganwall/adjustedcranlogs")

Function (there's only one)

  • adj_cran_downloads() Wrapper around cranlogs function cran_downloads(). Works the same, but returns a data frame showing the adjusted downloads, adjusted total downloads, shared minimum downloads, and package update information.

Usage

library(adjustedcranlogs)
library(ggplot2)
library(dplyr)
library(lubridate)

mypkgdownloads = adj_cran_downloads("skpr",from = "2017-08-15", to = "2017-11-15")

mypkgdownloads %>%
  ggplot() + 
  geom_line(aes(x=date,y=adjusted_total_downloads)) +
  geom_line(aes(x=date,y=total_downloads),color="red",linetype="dashed") +
  annotate("text",y=400,x=dmy("01-10-2017"),label="Raw Downloads",color="red") +
  annotate("text",y=50,x=dmy("20-10-2017"),label="Adjusted Downloads",color="black") +
  theme_minimal()

adjustedcranlogs's Issues

Error for sampledpriorpackages ?

I'm not sure why the code here has row()? It should be like below without the row?

sampledpriorpackages =  sample_n(priorpackages, number_to_compare, replace = TRUE)

Adjusted Total Downloads are Unstable

Hey there! I was interested in your package, but when I ran the example code on my package twice I got very different numbers of adjusted total downloads:

library(adjustedcranlogs)
library(ggplot2)
library(dplyr)
library(lubridate)

set.seed(1)
mypkgdownloads <- adj_cran_downloads("updog", 
                                     from = "2018-05-01",
                                     to = "2019-07-11")

mypkgdownloads2 <- adj_cran_downloads("updog", 
                                      from = "2018-05-01",
                                      to = "2019-07-11")

mypkgdownloads$adjusted_total_downloads[nrow(mypkgdownloads)]
mypkgdownloads2$adjusted_total_downloads[nrow(mypkgdownloads2)]

In the first case, I got 2082, in the second I got 1503.

Could this indicate a need to change some of the defaults?

Thanks!
David
