I wonder it works that far. It won't for me on Windows nor Linux, because
system2 passes the whole thing shQuoted to the shell. Hence it is highly

Well I was using the env argument to system2, which claims to be
cross-platform (at least for R and make). This command:
R_LIBS=/Users/hadley/R-dev R CMD INSTALL aL3xa-rapport-08e68ca/
is ok, isn't it?
You haven't said you were using the env argument, have you? If so, I missed
that part. I assumed you were specifying the above as the "command"
argument.
Hmmm, former message not quoted, as we ask in the posting guide. Where is
the reproducible example?
We seem to be having a bit of a communication breakdown. This is the
code that I run from the command line (on mac os x):
R_LIBS=/Users/hadley/R-dev R CMD INSTALL aL3xa-rapport-08e68ca/
# Desktop : R_LIBS=/Users/hadley/R-dev R CMD INSTALL aL3xa-rapport-08e68ca/
# * installing to library ‘/Users/hadley/R’
# ERROR: dependency ‘ascii’ is not available for package ‘rapport’
But:
ls /Users/hadley/R-dev/
# HandyStuff animation biOps mcmcTools mvbutils quantreg testthat
# SparseM ascii ggplot2 mturkr nstest scales whisker
It's hard to provide a reproducible example because it depends on
exactly what package you have installed where, but I had hoped that
this would at least illustrate my problem - R CMD install doesn't seem
to be respecting R_LIBS. I'm trying to understand whether this is a
bug, or something I don't understand correctly about R CMD INSTALL.
That's right, then you want (under Linux alikes):
system2("R", "CMD INSTALL package_version.tar.gz", env="R_LIBS=lib")
obviously.
Under Windows, you have to construct the shell command:
"set R_LIBS=lib& R CMD INSTALL package_version.tar.gz"
To clarify, system2 doesn't work in windows?
It does.

documentation has: " On Windows, ‘env’ is currently only supported for
commands such as ‘R’ and ‘make’ which accept environment variables on
their command line."
Yes, but "R CMD INSTALL" does not accept those variables in the command
line. This could perhaps be improved given someone finds some time to do it.
