- upstream update to 3.4.1
CHANGES IN R 3.4.1:
INSTALLATION on a UNIX-ALIKE:
* The deprecated support for PCRE versions older than 8.20 has been
removed.
BUG FIXES:
* getParseData() gave incorrect column information when code
contained multi-byte characters. (PR#17254)
* Asking for help using expressions like ?stats::cor() did not
work. (PR#17250)
* readRDS(url(....)) now works.
* R CMD Sweave again returns status = 0 on successful completion.
* Vignettes listed in .Rbuildignore were not being ignored
properly. (PR#17246)
* file.mtime() no longer returns NA on Windows when the file or
directory is being used by another process. This affected
installed.packages(), which is now protected against this.
* R CMD INSTALL Windows .zip file obeys --lock and --pkglock flags.
* (Windows only) The choose.files() function could return incorrect
results when called with multi = FALSE. (PR#17270)
* aggregate(, drop = FALSE) now also works in case of
near-equal numbers in by. (PR#16918)
* fourfoldplot() could encounter integer overflow when calculating
the odds ratio. (PR#17286)
* parse() no longer gives spurious warnings when extracting srcrefs
from a file not encoded in the current locale.
This was seen from R CMD check with inst/doc/*.R files, and check
has some additional protection for such files.
* print.noquote(x) now always returns its argument x (invisibly).
* Non-UTF-8 multibyte character sets were not handled properly in
