[ESS] how to compile shiny html

[Stephen Bond]

Hi folks,

I am trying to run the example from :
https://bookdown.org/yihui/rmarkdown/interactive-documents.html#intro-shiny

and I get an error:

/usr/bin/pandoc +RTS -K512m -RTS f2.knit.md --to html4 --from
markdown+autolink_bare_uris+tex_math_single_backslash --output f2-
exported.html --lua-filter /home/stephen/R/x86_64-pc-linux-gnu-
library/4.0/rmarkdown/rmarkdown/lua/pagebreak.lua --lua-filter
/home/stephen/R/x86_64-pc-linux-gnu-
library/4.0/rmarkdown/rmarkdown/lua/latex-div.lua --self-contained --
variable bs3=TRUE --standalone --section-divs --template
/home/stephen/R/x86_64-pc-linux-gnu-
library/4.0/rmarkdown/rmd/h/default.html --no-highlight --variable
highlightjs=1 --id-prefix section- --variable theme=bootstrap --
include-in-header /tmp/RtmpZfQj5e/rmarkdown-str9fc913622905.html --
mathjax --variable 'mathjax-url:
https://mathjax.rstudio.com/latest/MathJax.js?config=TeX-AMS-MML_HTMLorMML'
 
File shared/selectize/css/selectize.bootstrap3.css not found in
resource path
Error: pandoc document conversion failed with error 99

the file is in:
$ find ~ -name *.bootstrap3.css
/home/stephen/R/x86_64-pc-linux-gnu-
library/4.0/shiny/www/shared/selectize/css/selectize.bootstrap3.css

and I tried adding 
css: "/home/stephen/R/x86_64-pc-linux-gnu-
library/4.0/shiny/www/shared/selectize/css/"
resource-path: "/home/stephen/R/x86_64-pc-linux-gnu-
library/4.0/shiny/www/shared/selectize/css/"

in the meta section, but it did not do much. then I tried adding to my
pandoc setup in .emacs and that simply got ignored, I did not see the
option listed in the *polymode export* buffer. I tried this:

 '(markdown-command
   (concat "pandoc" " --from=markdown --to=html" " --standalone --
mathjax --highlight-style=pygments" " --resource-
path=/home/stephen/R/x86_64-pc-linux-gnu-library/4.0/shiny/www/"))


Does anybody know how to get around this? I had posted a question to
the RStudio community once and got booted very quickly when they saw I
was not using RStudio.
Thanks everybody
Stephen
