Subject:	[R] Removing columns from data frame

Hello,

Is there an easy way to remove a few columns from a data frame by 
indicating the column names? I am thinking of an operator like the "-" to 
remove the columns when referenced by column number, and I don't want to 
use the %in% operator together with the names() function.

Thanks
Daniel Mastropietro
