pamr.confusion {pamr} | R Documentation

## A function giving a table of true versus predicted values, from a nearest shrunken centroid fit.

### Description

A function giving a table of true versus predicted values, from a nearest shrunken centroid fit.

### Usage

    pamr.confusion(fit, threshold, extra=TRUE)

### Arguments

`fit` | The result of a call to pamr.train or pamr.cv
`threshold` | The desired threshold value
`extra` | Should the classwise and overall error rates be returned? Default TRUE

### Details

`pamr.confusion` Gives a cross-tabulation of true versus predicted classes for the fit returned by pamr.train or pamr.cv, at the specified threshold.

### Examples

    set.seed(120)
    x <- matrix(rnorm(1000*20),ncol=20)
    y <- sample(c(1:4),size=20,replace=TRUE)
    mydata <- list(x=x,y=y)
    mytrain <-   pamr.train(mydata)
    mycv <- pamr.cv(mytrain,mydata)
    pamr.confusion(mytrain,  threshold=2)
    pamr.confusion(mycv,  threshold=2)
