Description

Plot an evimp object.

Usage

## S3 method for class 'evimp':
plot(x = stop("no 'x' arg"),
    cex.var = 1,
    type.nsubsets = "l", col.nsubsets = "black", lty.nsubsets = 1,
    type.gcv = "l", col.gcv = "lightblue", lty.gcv = 1,
    type.rss = "l", col.rss = "gray60", lty.rss = 1,
    cex.legend = 1, x.legend = nrow(x), y.legend = x[1,"nsubsets"],
    main = "Variable importance", do.par=TRUE, ...)

Arguments

x

An evimp object.

cex.var

cex for variable names. Default is 1. Make smaller (say 0.8) if you have lots of variables.

type.nsubsets

Plot type for nsubsets graph. Default is "l". Use "n" for none, "b" looks good too.

col.nsubsets

Color of nsubsets line. Default is "black".

lty.nsubsets

Line type of nsubsets line. Default is 1.

type.gcv,col.gcv,lty.gcv

As above but for the gcv plot

type.rss,col.rss,lty.rss

As above but for the rss plot

cex.legend

cex for legend strings. Default is 1. Make smaller (say 0.8) if you want a smaller legend.

x.legend

x position of legend. Use 0 for no legend.

y.legend

y position of legend.

main

Main title. Default is "Variable importance".

do.par

Call par() for global settings as appropriate. Default is TRUE, which sets oma=c(bottom.margin,0,0,3), cex=cex.var. Set to FALSE if you want to append figures to an existing plot.

...

Extra arguments passed to plotting functions.
