R: Graphical table of best subsets

plot.regsubsets {leaps} | R Documentation

## 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

    ## S3 method for class 'regsubsets'
    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

### Value

None
