I?ve installed R 3.7.0 on a new laptop running macos 10.14.5 and have managed to get most of my usual packages to compile from source with a ~/.R/Makevars file that looks like this: CC=/usr/local/clang8/bin/clang CXX=/usr/local/clang8/bin/clang++ LDFLAGS=-L/usr/local/clang8/lib CPPFLAGS=-I/usr/local/clang8/include -I/opt/X11/include/freetype2 FC=/usr/local/gfortran/bin/gfortran FLIBS=-L/usr/local/gfortran/lib -lgfortran As usual, the last challenge seems to be to get rgl installed.

Hi all, I would like to know if there is any way to evaluate the values in `Sys.setenv` before setting the environment variables. For example, if we want to add a path to the environment variable `PATH`, we can do this in a terminal ``` > export PATH=~/mypath:$PATH > echo $PATH /Users/jeff/mypath:... ``` However, this style of assignment is not allowed in `Sys.setenv`, it treats its

...and the shell metacharacters. Instead, you need to do the corresponding computations in R, e.g. > paste(path.expand("~/mypath"), Sys.getenv("PATH"), sep=":") [1] "/Users/pd/mypath:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/gfortran/bin:/usr/local/clang8/bin:/Library/TeX/texbin:/opt/X11/bin" which you can then pass to Sys.setenv(). -pd > On 28 Aug 2020, at 11:00 , Jeff King <szwjf08 at gmail.com> wrote: > > Hi all, > > I would like to know if there is any way to evaluate the values in > `Sys.setenv` before setting...
