  1. R/Packages Downloads

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:  128,598 (8% down from October)

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. Most users are always upgrading to newer versions of R.

R Packages Downloads:  74,764,832(0.5%  up from October)

Package downloads slightly increased this November compared to October.

Figure 4 is a chart that shows the daily download variation of R packages in November.

Ratio of Base R downloads to R Package downloads: 1 : 581

Thus, for each download of base R, there are over 581 extension packages downloaded. The use of R still depends largely on extension packages.
