PlotContribution: Plot Cumuative Transcriptome Index

In myTAI: Evolutionary Transcriptomics

Description

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

Usage

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.
