A cool feature of select_ I discovered accidently is that you can pass in a vector of column names to get the corresponding columns, which is
much
easier than abusing which() to lookup indices.

Not sure if I'm misunderstanding, but you've always been able to slice on a vector of column names.
cols <- c("colA", "colB") dataframe[, cols]

True, although not as a part of a dplyr chain, which is cleaner.

extract and extract2 from magrittr also work. I do normally use dplyr though.
