clear screen?
...g this routine for several years. I?m sorry, I don?t remember where I got it. It works as it should, viz. it blanks the R console.

Thanks to Erich, the program now works like a charm. However, some cells contain formulae such as "832.1 * E4 * E3"  (yes I know: big, big *sigh*)...

control L to clear the Rgui screen in Windows
Greetings R-ians: Searching the Searchable Mail Archives I discovered that ctrl L will clear the Rgui screen, which is what I'd like to do from a print (or some similar) statement. Is there a mechanism to use the ctrl L clear-screen sequence in a script, or print statement? Thanks for your counsel. Charles Annis, P.E.
