Simple pariwise comparisons on exon expression data

Description

Get fold change t test p score for each probeset between a pair of arrays.

Usage

 
 pc(x,group,members)
 fc(object)
 tt(object)

Arguments

x expression data
group the column to select on
members vector of length 2 of column entries to compare between
object a pairwise comparison object of class PC as produced by pc

Details

Takes the expression data in x, use the column named 'group' in its phenotypic data and compare between the two groups of arrays defined by 'members'. fc,tt can be used to extract the fold chages and p-scores out of the resultant object.

Value

A PC object
