this is an empty data.frame I get back from a sql statement that
returns an empty result set. How can I create such an empty data.frame
using the data.frame() constructor?
I want to have a data.frame with 0 rows but named empty columns.
Is this what you want?
x <- data.frame(a=character(0), b=numeric(0))
x
[1] a b
<0 rows> (or 0-length row.names)
names(x)
[1] "a" "b"
