## A function to plot the cross-validated sample probabilities from
the nearest shrunken centroid
classifier

### Description

A function to plot the cross-validated sample probabilities from
the nearest shrunken centroid
classifier

### Usage

pamr.plotcvprob(fit, data, threshold)

### Arguments

`fit` |
The result of a call to pamr.cv |

`data` |
A list with at least two components: x- an expression
genes in the rows, samples in the columns), and y- a vector of
the class labels for each sample. Same form as data object
used by pamr.train. |

`threshold` |
Threshold value to be used |

### Details

`pamr.plotcvprob`

plots the cross-validated sample probabilities the from nearest shrunken
centroid classifier, stratified by the true classses.
