[R] Equivalent in R of the Contains operator in SAS

[Dan Abner]

Hi all,

I want to select all variables in the data.frame with a name that
includes are certain string. Something like the following:

merge3[,names(merge3) %in% c("Email","Email.x")]

But there are too many variations on the Email variable names to list them all.

Can anyone advise?

Thanks!

Dan
