orthogene is an R package for easy mapping of orthologous genes across hundreds of species.
Source code and Issues submission.
orthogene was created by Brian M. Schilder.
It pulls up-to-date interspecies gene ortholog mappings
across 700+ organisms.
It also provides various utility functions to map common objects
(e.g. data.frames, gene expression matrices, lists) onto
1:1 gene orthologs from any other species.
