delta: Estimating delta values from a distance matrix.

In HangRuan1912/phyExp: the R package for analyzing expression evolution based on RNA-seq data

Usage

estdelta(disMat = NULL)

Arguments

disMat

a distance matrix with column and row names

Value

returns a list of two, quartet: vector of delta numbers, each corresponded to a quartet in the distance matrix. taxa: matrix of delta numbers, colnames corresponded to taxaNames taxaNames: vector of taxaNames

Examples

data(tetraexp)
dis.mat <- expdist(tetraexp.objects, taxa = "all",
                     subtaxa = "Brain",
                     method = "pea")
deltas <- estdelta(dis.mat)
hist(deltas$quartet)
