Do you have the raw data or only the tabulated counts?

If you have the raw data, see ?table for ways to create n-dimensional
tables.

If you only have the tabulated counts, then you can use matrix():

> mat <- matrix(c(601, 290, 408, 2655), ncol = 2)
> dimnames(mat) <- list(c(0, 1), c(0, 1))

> mat
    0    1
0 601  408
1 290 2655


See ?matrix for more information.
