The data for this section is obtained through the API of METACRAN’s service that could be found here:
METACRAN obtains the download summaries from the RStudio CRAN mirror taken from http://cran-logs.rstudio.com/ This is one very popular download mirror for the R language due to the popularity of the RStudio IDE for R.
Base R downloads: 61,715 (10% up from July)
The chart in Figure 2 shows the distribution of base R downloads among the computer operating systems from which R was downloaded.
The chart in Figure 3 shows the number of downloads by R versions. From the chart, it is clear that there are users of R that still make use of older R versions e.g. version 2.x.x series.
R Packages Downloads: 41,935,159 (1% down from July)
Package downloads have dropped steadily for two months in our series now.
Figure 4 is a chart that shows the daily download variation of R packages in August.
Ratio of Base R downloads to R Package downloads: 1 : 679
Thus, for each download of base R, there are over 679 extension packages downloaded. The use of R still depends largely on extension packages.
Figure 5 is a chart visualizing the ratio of Base R downloads to R packages downloads
