plot.msda: 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 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
