pTAI {myTAI}

Compute the Phylostratum Contribution to the Global Transcriptome Age Index

Description

This function takes a standard ExpressionSet object and computes the partial contribution of the different phylostrata (ps) to the global Transcriptome Age Index profile.

Usage

pTAI(ExpressionSet)

Arguments

ExpressionSet

a standard PhyloExpressionSet object.

Details

This way of computing the partial contribution of the different phylostrata (ps) to the global Transcriptome Age Index profile was introduced by Domazet-Loso and Tautz, 2010. This function (pTAI) computes the partial TAI contribution for each phylostratum and each developmental stage and returns a data matrix storing the partial TAI contribution value for each phylostratum and each developmental stage.
