get_enc: Calculate ENC

In cubar: Codon Usage Bias Analysis

Calculate ENC

Description

get_enc computes ENC of each CDS

Usage

get_enc(cf, codon_table = get_codon_table(), level = "subfam")

Arguments

cf	matrix of codon frequencies as calculated by count_codons().
codon_table	codon_table a table of genetic code derived from get_codon_table or create_codon_table.
level	"subfam" (default) or "amino_acid". For which level to determine ENC.

Value

vector of ENC values, sequence names are used as vector names
