Description

This function computes the cumulative contribution of each Phylostratum or Divergence Stratum to the global TAI or TDI profile.

Usage

1
2
PlotContribution(ExpressionSet, legendName = NULL, xlab = "Ontogeny",
  ylab = "Transcriptome Index", main = "", y.ticks = 10)

Arguments

ExpressionSet

a standard PhyloExpressionSet or DivergenceExpressionSet object.

legendName

a character string specifying whether "PS" or "DS" are used to compute relative expression profiles.

xlab

label of x-axis.

ylab

label of y-axis.

main

main title.

y.ticks

a numeric value specifying the number of ticks to be drawn on the y-axis.

Details

Introduced by Domazet-Loso and Tautz (2010), this function allows users to visualize the cumulative contribution of each Phylostratum or Divergence Stratum to the global Transcriptome Age Index or Transcriptome Divergence Index profile to quantify how each Phylostratum or Divergence Stratum influences the profile of the global TAI or TDI pattern.
