In orQA: Order Restricted Assessment Of Microarray Titration Experiments

Description

Translate results from e2test into trinomial coding where 1 signifies an upward trend, 0 a none significant result, and -1 a downward trend.

Usage

sigdirE2test(o,alpha)

Arguments

o	result object from e2test
alpha	desired alpha level for the test

Details

groups <- rep(1:4,each=18)
ind <- rep(rep(1:3,each=6),4)
tdir <- sample((1:3)-2,100,rep=TRUE)
data <- matrix(rnorm(7200),nc=72)+(tdir %*% t(groups))
out <- e2test(data,groups,B=1000,rep=ind)
sigdir <- sigdirE2test(out)
table(sigdir)
