You start from a false premise, and it seems that you are reporting a
serious bug in Rpy to the wrong list:
Note that R expects to be run with the locale category `LC_NUMERIC' set
to its default value of C, and so should not be embedded into an
application which changes that.
('Writing R Extensions').

Thanks for the quick answer.
The documentation for Sys.setlocale mentions the possibility of warning
when LC_NUMERIC is set.
After checking it is looking like setting LC_NUMERIC from Sys.setlocale
does issue a warning, but there is does not seem to be a warning when
LC_NUMERIC is set in the parent shell. In the case the later is likely
to cause trouble, would it be appropriate to issue a warning when R is
initialized ?
Of course R does not violate its own documentation. None of the R
executables reset the LC_NUMERIC locale category, and all C programs start
in the 'C' locale (both facts you should have known from the homework
you did before posting).

Dear list,
A problem with creating pdf or postscript plots from an embedded R, and
in an environment where a locale is defined, was recently reported on
the rpy (Python->R interface) mailing list.
The problem appears to be that whenever the locale defines ',' as a
separator for the decimal part of a numerical value, the pdf/ps file
generated still has the ',' instead of a '.' causing problem when open
the resulting file with a postscript/pdf viewer.
Of course, an obvious workaround would be to force the locale for
numbers to C ( LC_NUMERIC = "C" ), but that could be overriding
internationalization features otherwise in R.
Any advice ?
Don't set LC_NUMERIC with R: ?Sys.setlocale did warn you about that.
It used to cause far more problems than this.
