Dear all, I am trying to use R within Excel 97. Seems the VBA with Excel 97 does not recognize function "InStrRev" (it gives error message when I try to launch RExcel Help, just the same as that it doesn't recognize function "Replace"). A solution for frunction Replace has been provided (Ritter, Christian , http://mailman.csd.univie.ac.at/pipermail/rcom-l/2003-May/000005.html). I am wondering if someone has a solution for function InStrRev. Many thanks. Huan This message and any attachments (the "message") is\ intended so... {{dropped}}
