Dear all,
I'm trying to write a post_processor() for a custom rmarkdown format. The
goal of the post_processor() is to modify the latex file before it is
compiled. For some reason the post_processor() is not run. The
post_processor() does work when I run it manually on the tex file.
Any suggestions on what I'm doing wrong? Below is the relevant snippet of
the code. The full code is available at
https://github.com/inbo/INBOmd/blob/post_processor/R/rsos_article.R
https://github.com/inbo/INBOmd/blob/post_processor/inst/
rmarkdown/templates/rsos_article/skeleton/skeleton.Rmd
is an Rmd is a MWE that fails compile because the post_processor() is not
run.
I installed it and tried running it using
debug(INBOmd::rsos_article)
rmarkdown::render("skeleton.Rmd")
then after post_processor was defined, I set it to debug as well, and
could see that the post_processor was being run.
I didn't get useful output, because the LaTeXing failed (I don't have the
rsos.cls), but perhaps you've already fixed this problem, or perhaps it is
intermittent?

To call in the statistician after the experiment is done may be no more
than asking him to perform a post-mortem examination: he may be able to
say
what the experiment died of. ~ Sir Ronald Aylmer Fisher
The plural of anecdote is not data. ~ Roger Brinner
The combination of some data and an aching desire for an answer does not
ensure that a reasonable answer can be extracted from a given body of
data.
