[R-pkg-devel] Weird error on CRAN linux check

I installed huxtable in two environments, my own Fedora installation with R
3.5.0 and all my packages and in a fresh Ubuntu system with R 3.4.4 and an
empty library. In both cases, huxtable is unusable: every example I try
fails because it doesn't find the methods.

So it has nothing to do with R checks or CRAN scripts, and it seems
improbable to me that the error comes from a corrupted dependency.
