Thanks Rich for pointing me to the thoughts of Bill Venables and Brian Ripley (the great men of S-plus and R). Yes, I have become lazy as Bill says in the link you pointed out. I am certainly of the old school where I use <- in my normal coding in functions etc, <<- for assigning a variable to global environment, and = for arguments in a function. This new and easy RExcel approach made me think I could get away with = because it just looks easier. It seems to be stable for me? Also OpenOffice changes my <- to an arrow and hence another reason I tried this. I guess I can change the setting in openoffice calc to not change the <- to an arrow? Again, I appreciate your time and kind words. I think I am trying to young and reckless! Happens when you just hit 40X !!! Kind regards, M. Mario F.

behaviors inside argument lists. Check the archives for
