doVariableSelection | R Documentation |
This function performs variable selection on gene expression matrices. It can, for instance, remove genes with low variation.
doVariableSelection(exprMat, removeLowVaryingGenes = 0.2)
exprMat |
A matrix of gene expression levels. rownames() are genes, and colnames() are samples. |
removeLowVaryingGenes |
The proportion of low varying genes to be removed.The default is .2 |
A vector of row/genes to keep.
try(doVariableSelection(exprMat, removeLowVaryingGenes = 0.2))
