I have installed the graphite package according to the instructions---namely, by running biocLite("graphite")---and it installs and I can load it. However, basic functions (eg, pathways() or pathwayDatabases()) are not available, and sessionInfo() indicates that the installed version of graphite is 1.12.0, not 1.14.0 (the most recent version, according to the above link). How do I update my version of graphite and gain access to these functions? Thanks very much!

Use the current release version of R (3.2.0).

Dan: It's always the simple things, isn't it? Your suggestion worked like a charm; thanks so much!
