create_geneADj_and_mutM.R:
I have crated a sampstrat function that will generate integers to be used
a grouping labels for coloring sample points in MDS plots. You simply need
to supply the metadata table name and the name of the column you wish to
stratify the sample by. As an examples you can stratify by "histological
type". This will generate a new variable where the histological type
classification is now represented as an integer for each type. tumours of
the same histological type will be indicated by the same colour on MDS
plots when coloured according to the variable resulting from the sampStrat
output.
