2. R/Packages Downloads

The data for this section is obtained through the API of METACRAN‘s service.

METACRAN obtains the download summaries from the RStudio CRAN mirror taken from here. This is one very popular download mirror for the R language due to the popularity of the RStudio IDE for R.

Base R downloads: 117,610 (up 91% from August)

The chart below shows the distribution of base R downloads among the computer operating systems from which R was downloaded.

The chart to the right shows the number of downloads by R versions. From the chart, it is clear that there are R coders who 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: 58,503,751 (up 40% from August)

Package downloads suddenly increased this month.

The chart below shows the daily download variation of R packages in September.

 

Ratio of Base R downloads to R Package downloads: 1 : 497

Thus, for each download of base R, there are over 497 extension packages downloaded. The use of R still depends largely on extension packages.

This chart visualizes the ratio of Base R downloads to R packages downloads:

Sum of Downloads for Top 50 packages: 21, 656, 551 (up 37% from August)

Download contribution of Top 50 packages amongst other 12,000+ CRAN packages: 37%
(i.e, 37% of total R package downloads came from Top 50 packages in August)

Below is a chart showing the top 50 downloaded packages based on their download counts.

Sum of Downloads for Top 100 packages: 32,657,833 (up 38.6% from August)

Download contribution of Top 100 amongst other 12,000+ CRAN packages: 55.8%
(i.e, about 56% of R package downloads came from Top 100)
