[R-sig-ME] Fwd: Re: R-core post from jw1085 at wildcats.unh.edu requires approval

My only wild guess about this is that there are (still unresolved as
far as I know) issues with the latest version of Matrix on 32-bit
operating systems (unlikely unless you're using Linux, and even then
slightly rare).  If so (sessionInfo() will tell us this), reverting to
the previous version of Matrix (e.g. see ?devtools::install_version)
should help.
