Replacements for stdout and stderr guaranteed to be open in all versions of R
...R/trunk/src/gnuwin32/system.c
it would appear that R_Consolefile and R_Outputfile only point to open
files when CharacterMode == RTerm, not in GUI mode.
Therefore my question is, are there any replacements for stdout and
stderr that work across all versions of R?
All the best,
David.
