Estimate Amino Acid Usage Frequencies of CDSs.

Usage

est_aau(cf, codon_table = get_codon_table())

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.

Value

a data.table with amino acid frequencies of CDSs.

Examples

# estimate amino acid frequencies of yeast genes
cf_all <- count_codons(yeast_cds)
aau <- est_aau(cf_all)
print(aau)
