Hi!
Under Windows R is installed, but its bin folder is not added to the
system PATH variable. I know that this is handled properly under *nix
like systems and I wonder, why this is not the default also for the MS
Windows? I guess that for most users a shortcut on the desktop or
anywhere else is sufficient, but there are occasions when one expects to
able to lunch R from anywhere - say the Command prompt.
This is the normal behaviour of Windows applications. There are several
reasons, including length limits on the Windows PATH (which are
version-specific) and that shells are not normally used -- most Unix
shells hash the path contents so lookup is (almost) independent of the
number of applications on the path.
If you run a shell (e.g. the Command prompt) you can set the path for that
shell, and indeed I have my system setup to use a different path in shells
than used from the desktop).
Finally, those Windows installers that do add to the PATH frequently fail
to uninstall correctly.
