Ah, so you really are at a DOS prompt. R is designed to be run in
Windows, and this works in all versions of Windows available to me (XP and
2000, and WinME is obselete). The problem is your so-called `shell',
Solution 1 is to get a real shell (even a real OS).
Solution 2 is to edit the rw1070/bin/BATCH file and replace
system("Rterm.exe $R_opts < $infile > $outfile 2>&1");
system("Rterm.exe $R_opts < $infile > $outfile");
and realize that probably the warning and error messages will not get
diverted to the file.
If anyone knows definitively how to do this in command.com, please let
R-Windows at r-project.org now.
