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

In emeryyi/rome: Robust Mean Estimation

Description

Produces a coefficient profile plot of the coefficient paths for a fitted lrome object. This function is modified based on the plot function from the glmnet package.

Usage

## S3 method for class 'lrome'
plot(x, xvar = c("norm", "lambda"), color = FALSE, label = FALSE, ...)

Arguments

x	fitted lrome model
xvar	what is on the X-axis. "norm" plots against the L1-norm of the coefficients, "lambda" against the log-lambda sequence.
color	if TRUE, plot the curves with rainbow colors. FALSE is gray colors. Default is FALSE
label	if TRUE, label the curves with variable sequence numbers. Default is FALSE
...	other graphical parameters to plot

Details

A coefficient profile plot is produced.

Examples

data(FHT)
m1 = lrome(x=FHT$x,y=FHT$y)
par(mfrow=c(1,3))
plot(m1) # plots against the L1-norm of the coefficients
plot(m1,xvar="lambda",label=TRUE) # plots against the log-lambda sequence
plot(m1,color=TRUE)
