[R] Removing columns from data frame

[Tony Plate]

The answer to your question is probably "No".

You could do

x[,is.na(match(names(x), c("unwanted column names"))),drop=F]

or

x[ ,-match(names(x), c("unwanted column names"), nomatch=0),drop=F]

While

x[,!(names(x) %in% c("unwanted column names")),drop=F]

is a few characters shorter, but you said you don't want to do that... (why 
is that?)
