I am trying to initialize a data frame with column names a, b, c WITHOUT any data:
dfrm <- data.frame(a, b, c)
However, I keep getting the error:
"Error in data.frame(a, b, c) : object 'a' not found"
Any thoughts anyone?

How about `dfrm <- data.frame(a = NULL, b = NULL, c = NULL)`? – jazzurro Nov 12 '14 at 00:53

1@jazzurro: good idea but doesn't work. – Ben Bolker Nov 12 '14 at 00:54

That would make my column names X1, X2, X3 instead of a, b, c – Trung Tran Nov 12 '14 at 00:55

@BenBolker Thanks for that. Now Richard suggested the answer. I will have a look. :) – jazzurro Nov 12 '14 at 00:57
