Error running RunNMF()

[balthasar0810]

Dear all,

sorry for this potential trivial question. But:

RunNMF(spat, features = NULL, nfactors = 20, rescale = TRUE, reduction.name = "NMF") Error in loadNamespace(x) : there is no package called ‘NNLM’

results in this error. I have no idea what that's supposed to meann...

Thanks! Chris
