Hi,

I'm a novice R user, much more used to SAS.  My problem is pretty simple - basically, in a data frame, I have variables named
x1,....,x10 and y1,...,y10; and I would like to create r1 = x1 / y1 etc

Apologies if this is way too rudimentary - but I couldn't find any posts online which solve this exact issue.

Cheers,
Andre
