In lrutter/bigPint: BIG multivariate data Plotted INTeractively

Convert SummarizedExperiment to only contain defined genes

Description

Reduce a SummarizedExperiment object so that it only now contains a subset of genes.

Usage

convertSESubsetGenes(dataSE, geneList)

Arguments

dataSE	SUMMARIZEDEXPERIMENT | Summarized experiment format that can be used in lieu of data and dataMetrics
geneList	CHARACTER ARRAY | List of gene IDs to remain in dataSE

Value

A new dataSE object that is a subset of the input dataSE in that it now only contains the user-specified list of genes.

Examples

# Example: Read in example SummarizedExperiment object that originally
# contains 5604 genes. Reduce it to now only contain ten genes (specifically
# the ones with the lowest FDR).
