The old patch somewhat works.
http://trac.sagemath.org/sage_trac/attachment/ticket/11436/trac_11436.patch
It didn't apply automatically because the source in sage-5.0
looks a bit different now:
---------
def _read_in_file_command(self, filename):
r"""
Return the R command (as a string) to read in a file named
filename into the R interpreter.
EXAMPLES::
sage: r._read_in_file_command('file.txt')
'file=file("file.txt",open="r")\nsource(file)'
"""
return 'file=file("%s",open="r")\nsource(file)'%filename
---------
Changing to
> return
> 'file=file("%s",open="r")\nsource(file,print.eval=TRUE)'%filename
doesn't do the trick, however reverting back to the old way, does:
> return 'source("%s",print.eval=TRUE)'%filename
The error message in the notebook prints full %filename, however.
