R Project Updates
Updates from R Core:
-
configure
will usepkg-config
to find the flags to link tojpeg
if available (as it should be for the recently-releasedjpeg-9c
andlibjpeg-turbo
). (This amends the code added in R 3.3.0 as the module name injpeg-9c
is not what that tested for.) -
The
duplicated()
method for data frames is now based onlist
s (instead of string coercion). Consequentlyunique()
is better distinguishing data frame rows, fixing PR#17369 and PR#17381. -
Calling
names()
on an S4 object derived from"environment"
behaves (by default) like callingnames()
on an ordinary environment. -
The environment variable
R_MAX_VZISE
can now be used to specify the maximal vector heap size. On macOS, unless specified by this environment variable, the maximal vector heap size is set to the maximum on 16GB and the available physical memory. This is to avoid having theR
process killed when macOS over-commits memory.
