sTXI: Calculate Stratum-Specific Transcriptomic Index

Description

Calculate the stratum-specific transcriptomic index (sTXI) by summing pTXI values within each phylostratum.

Usage

sTXI(phyex_set, option = "identity")

Value

Matrix of sTXI values with strata as rows and identities as columns

Arguments

phyex_set

A PhyloExpressionSet object

option

Character string specifying calculation method: - "identity": Sum pTXI values within each stratum - "add": Cumulative sum across strata

Examples

# Calculate sTXI values
stxi_values <- sTXI(example_phyex_set, option = "identity")
stxi_cumsum <- sTXI(example_phyex_set, option = "add")
