The current R release candidate has a lack of protect bug (of very long standing) with respect to the R_print.na_string and R_print.na_string_noquote fields of the static R_print structure declared in Print.h. This shows up very occassionally as incorrect output from the following lines in reg-tests-2.R: x <- c("a", NA, "b") factor(x) factor(x, exclude="")

...ts */). > Radford Neal "Interesting" ... .. more serioulsy: Thank you, Radford! As this about garbage collection, I found I can pretty well reproduce the problem via something like x <- c("a", NA, "b") fx <- factor(x, exclude="") gctorture2(2, 5) r <- replicate(30, capture.output(print(fx))) stopifnot(r[,1] == r) # ^^^ fails because of bug but the R 3.2.1 release candidate probably really cannot be touched now, with something non-trivial like this. We'd be *very* happy to get such problems during alpha or beta testing...

...urces, especially in a UTF-8 locale: see ?Writing R Extensions? which now has a subsection on this topic. ? factanal() now returns the rotation matrix if a rotation such as "promax" is used, and hence factor correlations are displayed. (Wish of PR#12754.) ? The gctorture2() function provides a more refined interface to the GC torture process. Environment variables R_GCTORTURE, R_GCTORTURE_WAIT, and R_GCTORTURE_INHIBIT_RELEASE can also be used to control the GC torture process. ? file.copy(from, to) no longer regards it as an error to supply a...
