plot.evimp: Plot an evimp object (created by the evimp function)

In earth: Multivariate Adaptive Regression Splines

Plot an evimp object (created by the evimp function)

Description

Plot an evimp object.

Usage

## S3 method for class 'evimp'
plot(x = stop("no 'x' argument"),
    cex.var = 1,
    type.nsubsets = "l", col.nsubsets = "black", lty.nsubsets = 1,
    type.gcv = "l", col.gcv = 2, lty.gcv = 1,
    type.rss = "l", col.rss = "gray60", lty.rss = 1,
    cex.legend = 1, x.legend = nrow(x), y.legend = x[1,"nsubsets"],
    rh.col = 1, 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.
rh.col	Color of right hand axis label. Use rh.col=0 for no label, a workaround for when the label is mispositioned.
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.
