My colleagues and I are preparing a new submission of a package for
CRAN (https://github.com/glmmTMB/glmmTMB/tree/master/glmmTMB). We've
tested it on all the platforms we have access to: Travis/Linux (devel
and release), MacOS (release), Ubuntu 16.04 (release), win-builder
(devel and release), without any serious problems.
On CRAN's Debian test machine, we get an ERROR and a WARNING.
1. Can anyone suggest the best way to test/find a platform where we can
figure out what's going on? I haven't used R-hub: should I try that?
2. The specific problem is in the "downstream_methods" example:
<https://github.com/glmmTMB/glmmTMB/blob/master/glmmTMB/man/downstream_methods.Rd#L65-L67>
warp.lm <- glmmTMB(breaks ~ wool * tension, data = warpbreaks)
if (require(emmeans)) {
emmeans (warp.lm, poly ~ tension | wool)
}
the error is:
Loading required package: emmeans
Error in ref_grid(object, ...) :
Can't handle an object of class 'glmmTMB'
Use help("models", package = "emmeans") for information on supported
models.
Calls: emmeans -> ref_grid
Execution halted
I can imagine that this has something to do with environment/method
loading. If I run
example("downstream_methods", package="glmmTMB")
in an R console it works fine (even if glmmTMB isn't loaded).
I can reproduce the error if *without loading the glmmTMB package* I run
warp.lm <- glmmTMB::glmmTMB(breaks ~ wool * tension, data = warpbreaks)
if (require(emmeans)) {
emmeans (warp.lm, poly ~ tension | wool)
}
... but I don't see why the methods from a package wouldn't be loaded
when running its own examples ??
3. The other problem is in vignette building (see below). Any
suggestions for debugging since it doesn't seem to fail locally?
The lines indicated suggest some similar kind of method-access problem
<https://github.com/glmmTMB/glmmTMB/blob/master/glmmTMB/vignettes/model_evaluation.rmd#L94-L95>:
Anova(owls_nb1) ## default type II
Anova(owls_nb1,type="III")
Any suggestions welcome ...
cheers

Note that, since v0.1.6.2, DHARMa includes support for glmmTMB, but
there are still a few minor limitations associatd with this package.
Please see https://github.com/florianhartig/DHARMa/issues/16 for
details, in particular if you use this for production.
