error when using 'identifyCommunicationPatterns' function

[AlfredShawn]

Thanks for developing this powerful tool! I am testing with our own scRNAseq data. Everything works good by following the walkthrough vignette, until the 'identifyCommunicationPatterns' function:

nPatterns = 5
cellchat <- identifyCommunicationPatterns(cellchat, pattern = "outgoing", k = nPatterns)

Error in (new("standardGeneric", .Data = function (x) :
unused arguments (model = list("NMFstd", 5, 0), method = "nndsvd")

It looks like an error related to the calling of nmf function. Could you help debug this? Thanks!
