selectrankedlists {DrugVsDisease} | R Documentation

## Select Ranked Lists

### Description

Given a list with two elements, one containing ranklists for a set of regression models and the second containing the associated p-values. This function is used to extract a subset of the models.

### Usage

    selectrankedlists(ranklist, colsinc)

### Arguments

`ranklist` | List with two elements (as output from generate profiles): Ranklist: Matrix containing the ranks of gene expression. Rows containing the genes, columns the different profiles. Pvalues: Matrix containing the associated p-values to the differential expression profiles in Ranklist.
`colsinc` | Vector of integers containing the column references of the profiles to select.

### Details

Format of list provided to selectrankedlists is the same as is output from generateprofiles `generateprofiles`. The output from selectrankedlists can be used as input to the classify profile function `classifyprofile`.

### Value

`Ranklist` | Matrix containing the ranks of gene expression. Rows containing the genes, columns the selected profiles
`Pvalues` | Matrix containing the associated p-values to the differential expression profiles in Ranklist
