plot.msda: Plot coefficients from a "msda" object

In msda: Multi-Class Sparse Discriminant Analysis

Plot coefficients from a "msda" object

Description

Produces a coefficient profile plot of the coefficient paths for a fitted msda object.

Usage

## S3 method for class 'msda'
plot(x, xvar = c("norm", "lambda"), ...)

Arguments

x	fitted msda model
xvar	the variable on the X-axis. The option "norm" plots the coefficients against the L1-norm of the coefficients, and the option "lambda" plots the coefficient against the log-lambda sequence.
...	other graphical parameters to plot

Details

A coefficient profile plot is produced.
