Data for the trends and activities summarized here were obtained from popular websites used by the R community such as Google, GitHub, StackOverflow, Rstudio, METACRAN and R-Bloggers

  1. StackOverflow

Number of StackOverflow Questions tagged R: 4,565 (8%  down from July)

Number of Answers for R questions: 4,630 (3%  up from July)

Number of Comments for R questions: 9,018 (6% down from July)

Page Views for R questions: 172,295 (7% up from July)

  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 downloads61,715 (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.

Figure 2

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.

Figure 3

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.

Figure 4

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

Top Packages (August, 2018):

Sum of Downloads for Top 50 packages: 15, 804, 449  (3% up from July)

Download contribution of Top 50 packages amongst other 12,000+ CRAN packages: 37.7%

(i.e, over 37% of total R package downloads came from Top 50 packages in July)

Below is a chart in Figure 7 showing the top 50 downloaded packages based on their download counts.

Figure 7

Sum of Downloads for Top 100 packages:  23, 556, 539  (2% up from July)

Download contribution of Top 100 amongst other 12,000+ CRAN packages56.2%
