Produces a plot of the coefficient paths for a fitted PCLasso object.

Usage

## S3 method for class 'PCLasso'
plot(x, norm = TRUE, ...)

Arguments

x	Fitted PCLasso model.
norm	If TRUE, plot the norm of each group, rather than the individual coefficients.
...	Other graphical parameters to plot.

Examples

library("survival")

# load data
data(ExpMatrix)
data(survData)
data(PCGroup)

x <- ExpMatrix    
y <- Surv(time=survData[,"time"], event=survData[,"status"])

# fit the PCLasso model
fit1 <- PCLasso(x, y, group = PCGroup, penalty = "grLasso")

# plot the norm of each group
plot(fit1, norm = TRUE)

# plot the individual coefficients
plot(fit1, norm = FALSE)
