Plot loss matrix

Description

Plots the loss for different combinations of scaling (sigma) and weighting (pi) parameters.

Usage

## S3 method for class 'cornet'
plot(x, ...)

Arguments

x

cornet object

...

further arguments (not applicable)

Value

This function plots the evaluation loss (cvm). Whereas the matrix has sigma in the rows, and pi in the columns, the plot has sigma on the x-axis, and pi on the y-axis. For all combinations of sigma and pi, the colour indicates the loss. If the R package RColorBrewer is installed, blue represents low. Otherwise, red represents low. White always represents high.

Examples

n <- 100; p <- 200
y <- rnorm(n)
X <- matrix(rnorm(n*p),nrow=n,ncol=p)
net <- cornet(y=y,cutoff=0,X=X)
plot(net)
