OGSA (version 1.2.0)

outCount: outCount

Description

Counts outliers by the Tibshirani and Hastie method. Adds the ability to subtract for outliers in the normals using corr = TRUE

Usage

outCount (data, phenotype, tail='right', corr=FALSE)

Arguments

data

A matrix of nGene by nSample

phenotype

A vector of 0s and 1s of length nSample, where 1 = case, 0 = control

tail

Indicates whether outliers are up (right) or down (left) outliers

corr

Whether to correct for normal outliers

Value

A vector with outlier counts by gene

Examples

data(ExampleData)
# Set up Phenotype
phenotype <- pheno
names(phenotype) <- colnames(cnv)

#set up datalist
dataSet <- list(expr,meth,cnv)

# set up values for expr-meth-cnv in that order
tailLRL <- c('left', 'right', 'left')

outTibLRL <- outCallTib(dataSet, phenotype=pheno,
                         names=c('Expr', 'Meth', 'CNV'), tail=tailLRL)
