Let say, I have a character vector of arbitrary length:
Vector - c(a, b, c)
Using that vector I would like to create a matrix (with number of columns as 2)
with all pairwise combinations of those elements, like:
Vector - c(a, b, c)
Mat - rbind(c(a, b), c(a, c), c(b, c)); Mat # number of
Hi,
Look at ?combn
t(combn(Vector, 2))
gives:
[,1] [,2]
[1,] a b
[2,] a c
[3,] b c
No idea how it is speed-wise.
HTH,
Josh
