getSampleOutlier(profileMatrix, sample.name)

## S4 method for signature 'matrix,nuchar'
getSampleOutlier(profileMatrix, sample.name)

## S4 method for signature 'OPPARList,nuchar'
getSampleOutlier(profileMatrix, sample.name)

Arguments

profileMatrix

A matrix of 0, -1 and 1 representing outlier genes in samples. Also an object of type OPPARList.

sample.name

A character vector containing one or more sample names, or a numeric vector containing sample indices.

Value

# Outlier profile for sample "GSM1124929"
getSampleOutlier(bcm.opa, "GSM1124929")

# Also can use sample index, instead of sample name
getSampleOutlier(bcm.opa, 11)

# A vector of sample names/indices are accepted as well
getSampleOutlier(bcm.opa, c(1,2))
getSampleOutlier(bcm.opa, c("GSM1124929","GSM1124941"))
