Subject: [Rd] object not found whilst loading namespace
Message-ID: <AANLkTinPXqDcByoT3_pqjWcYnUqB50R-RrB-e_G2BSCB@mail.gmail.com>

I've been updating a package and, when installing a local devel
version, I get an error "object 'confusionMatrix' not found whilst
loading namespace". Looking around online, it appears that this might
be related to loading a specific RData file, but it doesn't seem to be
the case AFAICT.

I've installed the devel version in the last week without issues and
the confusionMatrix code has been touched in a while.

Thanks,

Max
