simplifyMatrix: Simplify matrix in case of single row/columns

In BioQC: Detect tissue heterogeneity in expression profiles with gene sets

Description

Simplify matrix in case of single row/columns

Usage

simplifyMatrix(matrix)

Arguments

matrix

A matrix of any dimension If only one row/column is present, the dimension is dropped and a vector will be returned

Examples

testMatrix <- matrix(round(rnorm(9),2), nrow=3)
simplifyMatrix(testMatrix)
simplifyMatrix(testMatrix[1L,,drop=FALSE])
simplifyMatrix(testMatrix[,1L,drop=FALSE])
