OGSA (version 1.2.0)

copaInt: copaInt

Description

Counts outliers by Tibshirani-Hastie method by calling outCount after setting up list or by rank outlier method by calling outRank

Usage

copaInt(dataSet, phenotype, tails, thres = 0.05, method='Tibshirani',
corr=FALSE, offsets=NULL)

Arguments

dataSet

Set of matrices of molecular data

phenotype

Vector of 1 for case, 0 for control

tails

Vector equal to number of matrices with values left or right for where to find outliers

thres

alpha value

method

Tibshirani , Rank

corr

Whether to correct for normal outliers

offsets

A vector equal to the number of matrices which sets the 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 values for expr-meth-cnv in that order
tailLRL <- c('left', 'right', 'left')

#setup dataSet
dataSet <- list(expr, meth, cnv)

tibLRL <- copaInt(dataSet, phenotype, tails=tailLRL)
