Methods for TailRankTest objects

Description

This file describes the methods for an object of the class TailRankTest class.

Usage

## S4 method for signature 'TailRankTest':
summary(object, ...)
## S4 method for signature 'TailRankTest':
hist(x, overlay, ...)
## S4 method for signature 'TailRankTest':
as.logical(x, ...)
## S4 method for signature 'TailRankTest':
getStatistic(object,...)

Arguments

x A TailRankTest object
object A TailRankTest object
overlay An optional logical flag; defaults to FALSE.
... Extra graphical parameters

Value

as.logical Returns a logical vector. TRUE values pick out candidate biomarkers where the tail-rank test statistic exceeds the significance cutoff.
getStatistic Returns the vector of tail-rank statistics contained in object.
hist Invisibly returns the TailRankTest object.
summary Invisibly returns the TailRankTest object.

Examples

# generate some fake data to use in the example
nr <- 40000
nc <- 110
fake.data <- matrix(rnorm(nr*nc), ncol=nc)
fake.class <- rep(c(TRUE, FALSE), c(40, 70))

# build an object
null.tr <-  TailRankTest(fake.data, fake.class)

# summarize the object
summary(null.tr)

# plot a histogram
hist(null.tr)
hist(null.tr, breaks=70, col='blue', overlay=TRUE)

# get a logical vector that can select those markers
# identified by the test
selector <- as.logical(null.tr)
