nc.adj | R Documentation |
The adjusted Nc is f(gc3s) - Nc
nc.adj(nc, gc3)
nc |
a vector of length n with the effective number of codons for genes |
gc3 |
a vector of length n with corresponding GC composition at third codon positions |
The adjusted Nc is calculated as described in dos Reis et al. (2004).
