Codon usage
aminoacyl is a list containing the codon counts of 36 genes encoding yeast aminoacyl-tRNA-synthetase(S.Cerevisiae).
data(aminoacyl)
aminoacyl is a list containing the 5 following objects:
is a vector giving the gene names.
is a vector giving the cellular localisation of the proteins (M = mitochondrial, C = cytoplasmic, I = indetermined, CI = cyto and mito).
is a vector containing the 64 triplets.
is a factor giving the amino acid names for each codon.
is a dataframe containing the codon counts for each gene.
