Real programming, I think, is...

July 12, 2015
By

A small update to RcppRedis arrived on CRAN a few days ago. One of the unit tests failed as we (still) initialized the rredis package (loaded only for a comparison) in a form long-internalized by Bryan Lewis, its author. No actual changes to function...
