I misread this the first time, so maybe others did too.  Here's more

1.  shell.exec() should work in all Win32 versions.  For example,
will open the web page in the default browser (assuming only that the
browser is installed properly).

2.  shell('start http://www.r-project.org') could work in any Win32
version, but the user might have changed the path, or the shell, so it
won't necessarily.
