R: Plot an evimp object (created by the evimp function)

plot.evimp {earth} | R Documentation

## 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.
