plot_PRC

Description

plot_PRC

Usage

plot_clf_PRC(
  y,
  rf_clf_model,
  positive_class = NA,
  prefix = "train",
  outdir = NULL
)

Arguments

y	A factor of classes to be used as the true results
rf_clf_model	A list object of a random forest model.
positive_class	an optional character string for the factor level that corresponds to a "positive" result (if that makes sense for your data). If there are only two factor levels, the first level will be used as the "positive" result.
prefix	The prefix of data set.
outdir	The output directory.
