plot.compCL {Compack}R Documentation

Plot solution paths from a "compCL" object.

Description

Produce a coefficient profile plot from a fitted "compCL" object.

Usage

## S3 method for class 'compCL'
plot(x, xlab = c("lam", "norm"), label = FALSE, ...)

Arguments

x

fitted "compCL" model.

xlab

what is on the X-axis. "lam" plots against the log-lambda sequence (default) and "norm" against the L1-norm of the coefficients.

label

if TRUE, label the curve with the variable sequence numbers. Default is FALSE.

...

other graphical parameters.

Details

A coefficient profile plot for the compositional predictors is produced.

Value

No return value. Side effect is a base R plot.
