You can use system() or shell(), which adds "cmd.exe /c " to the front of your command so you can use DOS syntax. Remember to add double quotes when file names have spaces in them. E.g., I can call an old version of R with the following and later read its text output into my current session. >

Hi Ista, Thanks for the suggestion. I didn't know mapply can be used this way! Let me take one more step. Instead of defining a pattern for each string, I would like to define a set of patterns from all the possible combination of the unique values of those variables. Then I need each string to
