cvms 1.7.0

plot_confusion_matrix():

• Adds option to set intensities of main tiles by row_percentages or col_percentages. Sum tiles cannot be set by these. Idea from Elliot.

• Fixes error when the input has been filtered (for asymmetrical plotting) and add_sums=TRUE and/or diag_percentages_only=TRUE. Thanks @jwang-lilly for reporting.
