Dear R-helpers, I would like to adapt the following code
> names(data)<-sub("M","MOLE",names(data)) which changes any occurrence of "M" (in my variable names) to "MOLE" such that it ONLY operates on the first character of each variable name, i.e. M will only be changed to MOLE if it's the first character of a variable. I would appreciate any help you might provide. Thanks!
