⚠️There's a newer version (1.6.9) of this package.Take me there.

rphast (version 1.1)

RPHAST: R interface to PHAST

Description

RPHAST is an R interface to the PHAST pacakge (Phylogenetic Analyis with Space/Time Models). It can be used for many types of analysis in comparative and evolutionary genomics, such as estimating models of evolution from sequence data, scoring alignments for conservation or acceleration, and predicting elements based on conservation or custom phylogenetic hidden Markov models. It can also perform many basic operations on multiple sequence alignments and phylogenetic trees.
