plot.regsubsets: Graphical table of best subsets

In leaps: Regression Subset Selection

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

Arguments

x	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
...	other arguments
