Plots for Logic Regression

Description

Makes plots for an object of class logregmodel fitted by logreg.

Usage

## S3 method for class 'logregmodel'
plot(x, pscript=FALSE, title=TRUE, nms, ...)

Arguments

`x`	object of class `logregmodel`, typically a part of an object of class `logreg`, which is the result of the function `logreg`.
`pscript`	if `TRUE` all plots will be stored in postscript files with distinct names.
`title`	if `TRUE` this generates a title for some plots, typically listing the number of trees and the model size.
`nms`	names of variables. If `nms` is provided variable names will be plotted, otherwise indices will be used.
`...`	graphical parameters can be given as arguments to plot.

Value

The fitted trees are plotted.

Examples

data(logreg.savefit1)
# myanneal <- logreg.anneal.control(start = -1, end = -4, iter = 25000, update = 1000)
# logreg.savefit1 <- logreg(resp = logreg.testdat[,1], bin=logreg.testdat[, 2:21],
#                type = 2, select = 1, ntrees = 2, anneal.control = myanneal)
# plot(logreg.savefit1)
plot(logreg.savefit1$model) # does the same
