Editorial

The ‘Editorial’ article from the 2019-2 issue.

On behalf of the editorial board, I am pleased to present Volume 12, Issue 1 of the R Journal and my second issue as the Editor in Chief. Since the last issue Simon Urbanek has joined the editorial board and we have made a few structural changes. First, the R Foundation has approved the R Journal having Associate Editors. This change will allow us to address the increase in submission volume. The addition of the new AE positions should help alleviate some of the workload the editors have been dealing with and will result in shorter turn-around times for submissions. Second, complete issues of the R Journal will no longer be published in a single pdf. The build process for the document was complex and time consuming and we were not seeing the volume of download that would justify the effort. Individual articles are still available and the issue layout is still shown in the “Current Issue” section of the web page.

1 In this issue

News from the R Foundation is included in this issue along with an update from the The R Foundation’s histoRicalg project, which documents historic and historical numerical algorithms and provides reference implementations in R. In addition, a reprint documenting the history of R, which was initially published in the History of Programming Languages. Finally, this issue features 25 contributed research articles that have been categorized below.
