In December, activities across the R ecosystem reduced from levels observed in November. This was notable in StackOverflow, meetup events, and in the downloads of R packages. The December holidays likely caused this general reduction in activities. However, the first two weeks in December saw great activity in meetup events. A summary of selected trends, activities, and insights for R language in December 2018 are presented.
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

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: 101,883 (26% down from November)
The chart in Figure 2 shows the distribution of base R downloads among the computer operating systems from which R was downloaded.
The table above gives a count of downloads by operating systems.
OS | Downloads | |
1 | NA | 311 |
3 | src | 3867 |
2 | osx | 22605 |
4 | win | 75100 |
The chart in Figure 3 shows the number of downloads by R versions. Many users installed the latest version – 3.5.2 – of R released in December. 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: 58,582,203 (27.6% down from November)
Package downloads decreased significantly this December compared to November. However, R packages were still downloaded above 1M times on the 25th of December.
Figure 4 is a chart that shows the daily download variation of R packages in December.
Ratio of Base R downloads to R Package downloads: 1 : 575
Thus, for each download of base R, there are over 575 extension packages downloaded. The use of R depends largely on extension packages.
