GlobalAncova.1gene {GlobalAncova}R Documentation

Test for differential gene expression for just one gene

Description

A squared t-statistic which is equivalent to a F-statistic is computed. Corresponding p-values and permutation p-values are provided.

Usage

GlobalAncova.1gene(xx, group, perm = 10000)

Arguments

xx A vector of gene expression data. The data should be properly normalized beforehand (and log- or otherwise transformed). Missing values are not allowed.
group A vector with the group membership information. In the given version group must be coded as 0-1.
perm The number of permutations to be used. The default is 10,000.

Value

A vector giving the F value, permutation p–value and theoretical p–value.

Note

For internal use.
