plot.regsubsets: Graphical table of best subsets

Description

Plots a table of models showing which variables are in each model. The models are ordered by the specified model selection statistic. This plot is particularly useful when there are more than ten or so models and the simple table produced by summary.regsubsets is too big to read.

Usage

plot.regsubsets(obj, labels=obj$xnames, main=NULL, scale=c("bic", "Cp", "adjr2", "r2"), col=gray(seq(0, 0.9, length = 10)))

Arguments

obj

regsubsets object

labels

variable names

main

title for plot

scale

which summary statistic to use for ordering plots

col

Colors: the last color should be close to but distinct from white
