Dear all,
Is there a less cumbersome way to rename a column by name (as opposed
to index) than --
names( X)[ names[ X] == "bob"]<-"sue"
I find this clearer:
X$sue <- X$bob
X$bob <- NULL
...or, essentially the same:
X <- within(X, {sue <-bob; rm(bob)})
Manipulating the names attribute should be more efficient, although
not by order of magnitudes, I think.
