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.

• help.search(topic) 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.

You can not use #tidyverse without base R. It's not a dichotomy. Pick the tools that make you most effective.

It's weird (amazing) when using #rstats to search my google drive files is easier than using google drive to search itself. https://t.co/R8mjZVmP6M
