I agree there. I believe the same effect can be achieved with
'transform'.
transform(X, sue = bob, bob = NULL)
Perhaps there are performance reasons for using the names() <- value
approach for very large data.frames?

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

?
A semi-related question: how does one get the index of a column by
name, something along the lines of col.index( X, "sue") ?
