PLSDA ROC plot

Description

A Receiver Operator Characteristic (ROC) plot for PLSDA models computed by adjusting the threshold for assigning group labels from PLS predictions.

Usage

plsda_roc_plot(factor_name, ycol = 1, ...)

Arguments

factor_name

(character) The name of a sample-meta column to use.

ycol

(character, numeric, integer) The column of the Y block to be plotted. The default is 1.

...

Additional slots and values passed to struct_class.
