What version of R were you using?  That bug report was from 0.99.0,
I think.

I think CMD check _is_ now supposed to accept --vsize and --nsize:

auk%  R CMD check --help
Usage: R CMD check [options] pkgs
...
  --vsize=N             set R's vector heap size to N bytes
  --nsize=N             set R's number of cons cells to N


However, it seems not to work correctly

ARGUMENT '{R_opts}' __ignored__

appears in *.Rout on Solaris, and only one of them is accepted.

In the check script we need

    --nsize=*)
      R_opts="${R_opts} ${1}" ;;
    --vsize=*)
      R_opts="${R_opts} ${1}" ;;

adding a couple of `$'.


On (t)csh I use something like.

env R_VSIZE=10M R CMD check GRASS
