[R-pkg-devel] rmarkdown vignette build failures?

[Ben Bolker]

   Follow-up.

* I was wrong about the reversion to an earlier SVN commit helping

* Sebastian Meyer provided **enormously** useful feedback in telling me 
that these are the steps required to replicate what "R CMD build" is 
doing internally when it fails

   tools::buildVignettes(dir = ".", tangle = TRUE)
   vigns <- tools::pkgVignettes(dir = '.', output = TRUE, source = TRUE)

* running this code interactively allowed me to see that my build was 
failing with these errors:

Error: processing vignette 'lmer.Rnw' failed with diagnostics:
Running 'texi2dvi' on 'lmer.tex' failed.
LaTeX errors:
! Package inputenc Error: Unicode character ┌ (U+250C)
(inputenc)                not set up for use with LaTeX.

* further digging showed that for some reason I **absolutely still do 
not understand**, a simple Rnw chunk that printed a data frame was for 
some reason finding a 'huxtable' package printing method and trying to 
print the table using weird Unicode outline characters (e.g. the U+250C 
complained about above was being used as a box-corner character)

* I still don't really understand what's going on, but I'm getting there ...

   cheers
