Semiparametric regression plotting

Description

Takes a fitted spm object produced by spm() and plots the component smooth functions that make it up, on the scale of the linear predictor.

Usage

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

Arguments

Details

Produces plots with each panel corresponding to a component of the semiparametric regression model.

Examples

library(SemiPar)
data(fossil)
attach(fossil)
fit <- spm(strontium.ratio~f(age))
plot(fit)

# Now do several customisations

op <- par(bg="white")
par(bg="honeydew")
plot(fit,ylim=range(strontium.ratio),col="green",
     lwd=5,shade.col="mediumpurple1",rug.col="blue")   
points(age,strontium.ratio,col="orange",pch=16)
