how do I create a data frame with the given column names

i.e., I have a vector of strings for names and I want to get an _EMPTY_
data frame with these column names.
is it at all possible?
It's not really clear to me what you want to do.
If you want to create a zero-rows dataframe (why?),
here's one way:
nm <- letters[11:14]
d <- as.data.frame(
matrix(nrow = 0, ncol = 4,
dimnames = list(NULL, nm)))
