When I use identifySignatures from somaticsignatures package it throws me out this error. What do I need to change ?

Hi, Aslam

I have encountered an exactly same problem. My code was working but I recently updated NMF packages (following biocLite suggestion). Then, when I ran the command, I had the error:

sigs_nmf = identifySignatures(sca_mm, n_sigs, nmfDecomposition)
Error in (new("standardGeneric", .Data = function (x)  : 
  unused arguments (model = list("NMFstd", 5, 0), method = "random")

Thank you for the report. I have not been able to reproduce this issue with the same package versions as you have. Could you please post a complete example that I can rerun (from the starting of the R session until the error occurs) together with a complete output of the sessionInfo command?
