lmSubsets (version 0.5-2)

plot.lmSubsets: Plot a subset regression

Description

Plot the deviance of the selected submodels, as well as a specified information criterion.

Usage

# S3 method for lmSubsets
plot(x, penalty = "BIC", xlim, ylim_rss, ylim_ic, type_rss = "o",
     type_ic = "o", main, sub, xlab, ylab_rss, ylab_ic, legend_rss,
     legend_ic, ann = par("ann"), axes = TRUE, lty_rss = c(1, 3),
     pch_rss = c(16, 21), col_rss = "black", bg_rss = "white",
     lty_ic = c(1, 3), pch_ic = c(16, 21), col_ic = "red",
     bg_ic = "white", ...)
# S3 method for lmSelect
plot(x, xlim, ylim, type = "o", main, sub, xlab, ylab, legend,
     ann = par("ann"), axes = TRUE, lty = 1, pch = 16, col = "red",
     bg = "white", ...)
