restrictFeatureMat R Documentation
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).
#' @examples
X <- matrix(1:25, nrow=5)
rownames(X) <- c("expA", "expB", "copC", "mutC", "expD")
restrictFeatureMat(geneSet = c("B", "C"), X)
