plot.vimp.rfcca {RFCCA}

Plot variable importance measures for rfcca objects

Description

Plots variable importance measures (VIMP) for subject-related z-variables for training data.

Usage

## S3 method for class 'rfcca'
plot.vimp(x, sort = TRUE, ndisp = NULL, ...)

Arguments

x

An object of class (rfcca,grow) or (rfcca,predict).

sort

Should the z-variables be sorted according to their variable importance measures in the plot? The default is TRUE.

ndisp

Number of z-variables to display in the plot. If sort= TRUE, the most important ndisp z-variables will be plotted. Otherwise, the first ndisp z-variables in the original call will be plotted. The default value is NULL which will plot all of the z-variables.

...

Optional arguments to be passed to other methods.

Value

Invisibly, the variable importance measures that were plotted.
