plot.swReg: Plot forward stagewise regression path

In marjoleinF/swReg: Perform forward stagewise regression

Description

plot.swReg plots non-zero coefficients for each iterations of forward stagewise regression.

Usage

## S3 method for class 'swReg'
plot(x, legend = TRUE, ...)

Arguments

x	an R object resulting from application of swReg
legend	logical. Should a legend be printed? Defaults to TRUE
...	not used

Value

A plot with iteration numbers on the x-axis and coefficient values on the y-axis,

Examples

## Example using Boston Housing data:
 library(MASS)
 X <- as.matrix(Boston[,-14])
 Y <- Boston$medv
 swReg1 <- swReg(X, Y, stepsize = .01)
 swReg2 <- swReg(X, Y, stepsize = .01, standardizeY = FALSE)
   
 ## Plot coefficient paths:
 par(mfrow=c(1,2))
 plot.swReg(swReg1)
 plot.swReg(swReg2)
