rcellminer (version 1.4.2)

restrictFeatureMat: Restricts a feature matrix to only include features associated with a specified gene set.

Description

Restricts a feature matrix to only include features associated with a specified gene set.

Usage

restrictFeatureMat(geneSet, featureMat, prefixSet = c("cop", "exp", "mut"))

Arguments

geneSet

a character vector of gene names.

featureMat

a matrix or data frame with feature vectors along rows and feature names specified in rownames(featureMat).

prefixSet

a set of feature name prefixes to be prepended to each element of geneSet to obtain a collection of geneSet-associated features.

Value

• a matrix containing the features in the intersection of rownames(featureMat) and the set of geneSet-derived features (obtained by prepending each element of prefixSet to each gene in geneSet).
