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.
