R Project Updates

Updates from R Core:

  • mclapply() gets an option affinity.list which allows more efficient execution with heterogenous processors, thanks to Helena Kotthaus.

  • Runing of finalizers after explicit GC request moved from the R interface do_gc to the C interface R_gc. This helps with reclaiming inaccessible connections.

  • and ??topic matching topics in vignettes with multiple file name extensions (e.g., *.md.rsp but not *.Rmd) failed with an error when using options(help_type = "html").

  • Writing R Extensions now mentiones the macros MAYBE_REFERENCED, MAYBE_SHARED, and MARK_NOT_MUTABLE that should be used by package C code instead NAMED or SET_NAMED.

  • If the option setWidthOnResize is set and TRUE, R run in a terminal using a recent readline library will set the width option when the terminal is resized. Suggested by Ralf Goertz.

  • If multiple on.exit epressions are set using add = TRUE then all expressions will now be run even if one signals an error.

  • array(character(), 1) now gives (a 1D array with) NA as has been documented for a long time as in the other cases of zero-length array initialization and also compatibly with matrix(character(), *). As mentioned there, this also fixes PR#17333.

  • x <- 1:2; tapply(x, list(x, x), function(x) "")[1,2] now correctly returns NA again. (PR#17333)

  • Reverted unintended change in behavior of return calls in on.exit expressions introduced by stack unwinding changes in R 3.3.0.
