pamr.listgenes {pamr} | R Documentation

## A function to list the genes that survive the thresholding, from the nearest shrunken centroid classifier

### Description

A function to list the genes that survive the thresholding, from the nearest shrunken centroid classifier produced by pamr.train

### Usage

    pamr.listgenes(fit, data, threshold, genenames=F)

### Arguments

`fit` | The result of a call to pamr.train
`data` | The input data. In the same format as the input data for pamr.train
`threshold` | The desired threshold value
`genenames` | Include genenames in the list? If yes, they are taken from "data". Default is false (geneid is always included in the list).

### Details

`pamr.listgenes` List the geneids, and standardized centroids for each class, for genes surviving at the given threshold.

    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,geneid=as.character(1:1000))
    mytrain <-   pamr.train(mydata)
    mycv <- pamr.cv(mytrain,mydata)
    pamr.listgenes(mytrain, mydata, threshold=1.6)
