A wild guess, based on some recent "non-deterministic" behavior in
lme4: could this be driven by a bug in optimized linear algebra libraries
(BLAS/LAPACK)? (Unfortunately, I'm not clear on how to check the versions
of BLAS/LAPACK being used and whether they are subject to bugs,
but perhaps so

I think that a logical option "strict" in the above meaning could be

For people who want to play with these, here are some functions that let
you get or set the "payload" value in a NaN. NaN and NA, Inf and -Inf
are stored quite similarly; these functions don't distinguish which of
those you're working with. Regular finite values give NA for the
payload value,
Hi all,
is there already a variable protection (as use else when linking to C/C++
e.g. PROTECT(a = AS_NUMERIC(a)); ) built in when using RcppExport from Rcpp?

Thanks Duncan. I have since found that building cairo and
adding '--with-cairo' to the configure command solves this
problem, and also gives (at least to my eyes) much nicer looking 2D png()
