calling NMF::nmf without library(NMF)

[gdkrmr]

When calling nmf from a fresh R session (without calling library(NMF) first):

ints_trn <- matrix(seq(0, 98, by = 2), ncol = 5)
tmp <- NMF::nmf(t(ints_trn), rank = 2, nrun = 10, seed = 13)

Gives the following error:

Error in path.package(pkg) : none of the packages are loaded

Package NMF is doing a lot of stuff in the background when is attached. The only way I found to be able to use it as a dependancy in another package, is to move it from the Imports section to the Depends section to have it attached insted of loaded.
