 plot.cosso R Documentation

## Plot method for COSSO object

### Description

Plot `L_2` norm solution path or main effects of selected functional components

### Usage

``````## S3 method for class 'cosso'
plot(x,M,plottype =c("Path","Functionals"),eps=1e-7,...)
``````

### Arguments

 `x` a cosso object. `M` a smoothing parameter value. Argument required when `plottype="Functionals"`. `plottype` either `Path` (default) or `Functionals`. The Path plot shows the `L_2` norm path for each functional component as a function of smoothing parameter M. The Functional plot shows the estimated functional components for each input variable at a particular smoothing parameter M. Abbreviations are allowed. `eps` an effective zero, default is `1e-7`. `...` additional arguments for plot generic.

### Examples

``````set.seed(20130310)
x=cbind(rbinom(200,1,.7),matrix(runif(200*7,0,1),nc=7))
trueProb=1/(1+exp(-x[,1]-sin(2*pi*x[,2])-5*(x[,4]-0.4)^2))
y=rbinom(200,1,trueProb)

B.Obj=cosso(x,y,family="Bin")
plot.cosso(B.Obj,plottype="Path")
plot.cosso(B.Obj,M=2,plottype="Func")
``````
