[Rd] R CMD check not reading R_LIBS from ~/.R/check.Renviron

[Gavin Simpson]

Dear List,

Further to my earlier email, I note that, for me at least, R CMD check
is *not* reading R_LIBS from ~/.R/check.Renviron on R 2.15.2 patched
(r61228) and R Under Development (r61660). The only way I can get R CMD
check to look for packages in a user-supplied library is by explicitly
exporting R_LIBS set to the relevant directory.

R CMD build *does* read R_LIBS from ~/.R/build.Renviron for the same
versions of R on the same Fedora 16 laptop. So I am in the strange
situation of being able to build but not check a source package having
followed the instructions in Writing R Extensions.

I have tried exporting R_CHECK_ENVIRON via

    export R_CHECK_ENVIRON=/home/gavin/.R/check.Renviron

and that doesn't work either.

~/.R/check.Renviron contains:

R_LIBS=/home/gavin/R/libs/
#R_LIBS=/home/gavin/R/devlibs/

Anyone suggest how/where I am going wrong?

More complete system info follows below.

TIA

Gavin
