[R] substitution matrix for amino acid

[Nora Muda]

Hi,
 
I want to compute the pairwise distances of amino acid
sequences and then construct the phylogenetic tree. I
noticed that ape package  support only for DNA
sequences and compute the pairwise distances by using
dist.dna function. Can anyone suggest what package
that support for protein sequences and then construct
the phylogenetic tree?
 
Thank you in advance for any help.
 
Nora.
