I need to run a bash command, but when you call system() the default shell
is sh (see my sessionInfo below).
I found the shell command (
http://www.stat.ucl.ac.be/ISdidactique/Rhelp/library/base/html/shell.html)
but it seems to be disappeared in current versions of R?
I am running all this from R CMD BATCH with "system" calls to other R
scripts.
For a little more info, I'm generating sphinx documents (a python
documentation library) through R and need to use a python virtual
environment.
So I need to call system('source bin/activate'), but "source" isn't a
recognized command in the sh shell...
Any help is appreciated,
Justin
