testPS: Performs PS (parsimony score) test on switch data

Description

testPS performs a PS test

Usage

testPS(
  switches,
  bylineage = FALSE,
  pseudocount = 0,
  alternative = c("less", "two.sided", "greater")
)

Value

A list containing a tibble with mean PS statistics, and another with PS statistics per repetition.

Arguments

switches

Data frame from findSwitches

bylineage

Perform test for each lineage individually? (FALSE)

pseudocount

Pseudocount for P value calculations

alternative

Perform one-sided (greater or less) or two.sided test

Details

Output data table columns: RECON = PS for observed data PERMUTE = PS for permuted data DELTA = RECON - PERMUTE PLT = p value for DELTA < 0 PGT = p value for DELTA < 0

• RECON: PS for observed data.

• PERMUTE: PS for permuted data.

• DELTA: RECON - PERMUTE.

• PLT: p value that DELTA < 0

• PGT: p value that DELTA > 0

• STAT: Statistic used (PS).

• REP: Bootstrap repetition.

• REPS: Total number of ootstrap repetition.
