Unable to reorder sample in plotMutProfile()

[xiw588]

I am trying to reorder the samples but it failed all the time with the following error
Error in if (names(sampleOrder)[i] %in% patient.id) { :
argument is of length zero

sampleOrder in the plotMutProfile() should refer to a list of the Tumor_Sample_Barcode in the order that I want to plot or something else?
