MyGene.R, our official R client for MyGene.info web services, was just released as part of Bioconductor 3.0! Thanks to the hard work of Adam Mark, and the great help from Ryan Thompson.

To install:

source("http://bioconductor.org/biocLite.R")  
biocLite("mygene")  

If you have an older version of Bioconductor installed, upgrade it first:

biocLite("BiocUpgrade")  

Your feedback is welcome!
