Hi,
I am trying to run 2 versions of R, 2.7.2. and 2.9.0, and am trying to use R
Switch on Mac OS Leopard 10.5.7
I have been following the second step and removing
/Library/Receipts/R-framework prior to installation of 2.9.0
Upon installing 2.9.0, 2.9.0 runs OK, but if I select 2.7.2 on Rswitch, the
following error results on startup (ERROR 1, below) and R crashes.
Upon installing 2.7.2 (after similarly removing R-framework), and choosing
R.2.9.0 on Rswitch, a slightly different error appears.
Any advice would be very much appreciated.
Regards,
Min-Han
