biocLite("greenelab/ADAGEpath")

if you have BiocInstaller already installed (and for impute, I believe this tends to be the case), it turns out that recent versions will do a smart install of github packages and dependencies where possible:

```
library(BiocInstaller)
biocLite("greenelab/ADAGEpath")
# BioC_mirror: https://bioconductor.org
# Using Bioconductor 3.6 (BiocInstaller 1.27.2), R 3.4.0 (2017-04-21).
# Installing github package(s) 'greenelab/ADAGEpath'
# ... time passes ...
# * installing *source* package ‘ADAGEpath’ ...
# ** R
# ** data
# *** moving datasets to lazyload DB
# ** inst
# ** preparing package for lazy loading
# ** help
# *** installing help indices
# ** building package indices
# ** installing vignettes
# ** testing if installed package can be loaded
# * DONE (ADAGEpath)
```

Turns out there are quite a few dependencies!
