Compute the Phylostratum Contribution to the Global Transcriptome Age Index
Source:R/pTAI.R
pTAI.RdThis function takes a standard ExpressionSet object and computes the partial contribution of the different phylostrata (ps) to the global Transcriptome Age Index profile.
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.
