hankel.Rmd not rendering due to bibtex issues

[urbach]

its not rendering for me

label: unnamed-chunk-11
Quitting from lines 142-156 (multi_particle_fit_test.Rmd) 
Error in rbind(gr(par = par, x = x, ...), grpriors) : 
  number of columns of matrices must match (see arg 2)

This leads Travis check to fail, I think...

No, the travis check fail is due to problems with biber which I've seen before on the HISKP institute machines when the version of biber was manually fixed by someone to a specific version:

add of symlinks had 1 error(s), see messages above.

INFO - This is Biber 2.14

INFO - Logfile is 'hankel.blg'

INFO - Reading 'hankel.bcf'

ERROR - Error: Found biblatex control file version 3.3, expected version 3.7.

This means that your biber (2.14) and biblatex (3.7) versions are incompatible.

See compat matrix in biblatex or biber PDF documentation.

That is another issue. But I was actually missing something in a list. And if you do higher_states$ampl and it is not there, you get NULL. And c(x, NULL) just gives x without an error or warning. This is now fixed and the biber issue remains.

[kostrzewa]

AFAIU, we need to use before_install in .travis.yml to set up the texlive environment with everything that is actually required for rendering all the vignettes that we have. Otherwise, it will attempt to download things as required and this seems to result in incompatible versions being installed.

https://yihui.org/tinytex/ is installed with the rmarkdown R package as far as I can see and it might well be that this is where the issues begin...

I have commented out the bibliography stuff in master such that we still get sensible results from Travis CI. Then we can work on this in a separate pull request.
