1. Remove the paths to Rtools and to R in PATH since they don't look correct.

2. Enter this from the Windows cmd line:

and it should show that TMP is set to %userprofile%\AppData\Local\Temp
and that TEMP is set to the same thing and TMPDIR is not listed.
If not change them so that it so reads.

3. Once you have done all the above then place this file anywhere on your path


The following will find R using the registry or if its not there it
will look in the usual places and then run it so you can then try:

R.bat CMD ...whatever...

If that still does not work proceed to the following manual alternative:

4. If the above did not fix the problem download this file


5. edit the SET statements in it and then place it on your Windows path.

6. Now run it from the cmd line:


and for the rest of that cmd line session your path should be set up correctly.

Also you might want to read:


There is also a new discussion group just set up at
that is also being used for the batchfiles.
