plot.gg_vimp: Plot a `gg_vimp` object, extracted variable importance of a `rfsrc` object

Description

Plot a gg_vimp object, extracted variable importance of a rfsrc object

Usage

# S3 method for gg_vimp
plot(x, relative, lbls, ...)

Value

ggplot object

Arguments

x: gg_vimp object created from a rfsrc object
relative: should we plot vimp or relative vimp. Defaults to vimp.
lbls: A vector of alternative variable labels. Item names should be the same as the variable names.
...: optional arguments passed to gg_vimp if necessary
