[R] Selecting data frame components by name - do you know a shorter way?

[Douglas Grove]

So you want to create a subset of a data frame?
with components "name1" "name2" "name3" ... 

dframe[, c("name1","name2","name3",...)]   

will do that

I suspect there must be an easy way to access components of a data frame by name, i.e. the input should look like "name1 name2 name3 ..." and the output be a data frame of those components with the corresponding names.
