[R-pkg-devel] vignette error in debian

Thu Nov 28 18:16:12 CET 2019

I was able to reproduce the vignette error in an R-devel session with this environment variable set. It came from a strange polygon() call with x and y arguments being matrices with list elements.

I cannot test at the moment. Maybe you condition on
class(something) == "matrix"
somewhere in your code? This should be replaced by 
inherits(something, "matrix")
since in future R, matrix objects also formally belong to the array class, so the class vector has length two. See the corresponding blog post by Martin Mächler for further details:

Cheers, Sebastian
