baseFreq: Summaries of alignments

In KlausVigo/phangorn: Phylogenetic Reconstruction and Analysis

Summaries of alignments

Description

baseFreq computes the frequencies (absolute or relative) of the states from a sample of sequences. glance computes some useful information about the alignment. composition\_test computes a \chi^2-test testing if the state composition for a species differs.

Usage

baseFreq(obj, freq = FALSE, all = FALSE, drop.unused.levels = FALSE)

## S3 method for class 'phyDat'
glance(x, ...)

composition_test(obj)

Arguments

obj, x	as object of class phyDat
freq	logical, if 'TRUE', frequencies or counts are returned otherwise proportions
all	all a logical; if all = TRUE, all counts of bases, ambiguous codes, missing data, and alignment gaps are returned as defined in the contrast.
drop.unused.levels	logical, drop unused levels
...	further arguments passed to or from other methods.

Value

baseFreq returns a named vector and glance a one row data.frame.
