Nope, it works as documented, using exactly the same code as on Linux.
You do not tell us your shell here (so I presume it is XP's cmd.exe), but
you seem to have set R_PROFILE to a string enclosed in quotes (as the R
output shows). Try
RGui.exe R_PROFILE=C:/fernando/R.profile
I am in the same boat, and so I use tcsh/sh on Windows to be sure I
understand the quoting rules.
