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!
Mark Na
