outRank {OGSA} | R Documentation

## outRank

### Description

Counts outliers by the Ghosh method.

### Usage

    outRank (dataSet, phenotype, thres= 0.05, tail='right', corr=FALSE,
    offsets=NULL)

### Arguments

`dataSet` | Set of matrices of molecular data
`phenotype` | Vector of 1 for case, 0 for control
`thres` | Alpha value
`tail` | Vector equal to number of matrices with values 'left' or 'right' for where to find outliers
`corr` | Whether to correct for normal outliers
`offsets` | Vector equal to number of matrices which sets minimum value relative to normal to call outlier (corrected rank only)

### Value

A vector with outlier counts by gene

### Examples

    data(ExampleData)

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

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

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

    outRankLRL <- outRank(dataSet, phenotype, thres= 0.05, tail=tailLRL,
                                 corr=FALSE, offsets=NULL)
