The Policy now links to an accompanying document on Using Rust in CRAN packages.

3 CRAN package submissions

From May 2023 to September 2023 CRAN received 12237 package submissions. For these, 20527 actions took place of which 14006 (68%) were auto processed actions and 6521 (32%) manual actions.

Minus some special cases, a summary of the auto-processed and manually triggered actions follows:

archive inspect newbies pending pretest publish recheck waiting
auto 3677 1889 2460 0 0 3734 1282 964
manual 2378 186 431 317 52 2423 599 135

These include the final decisions for the submissions which were

archive publish
auto 3573 (29.7%) 3246 (27%)
manual 2337 (19.4%) 2883 (23.9%)

where we only count those as auto processed whose publication or rejection happened automatically in all steps.

4 CRAN mirror security

Since the R 3.4.0 release, chooseCRANmirror() offers these mirrors in preference to the others which are not fully secured (yet).

5 CRAN Task View Initiative

There is one new task view:

Currently there are 44 task views (see, with median and mean numbers of CRAN packages covered 104 and 122, respectively. Overall, these task views cover 4496 CRAN packages, which is about 22% of all active CRAN packages.
