Trying to install r-stan without using rocker

| Hi All,
| 
| I?ve followed Dirk?s advice and am now starting from:
| 
| FROM eddelbuettel/r2u:22.04
| While installing rstan using
| RUN Rscript -e 'install.packages(c("rstan", "stringr", "gtools", "tidyr"))'

(BTW I would actually use

   RUN install.r rstan stringr gtools tidyr

which is more idiomatic _for me_ using littler, but equivalent <wink> )

| I can now get my lambda function running,

Nice!

| but it throws an error when opening my Stan model, namely: 
| "C++ compiler not found on system.?
| 
| I would have thought that it would be part of this base image.

Indeed. That r2u image has g++-11.

So (r)stan may be configured differently / may have seen / expected a
different compiler?  I would check its docs. You should be able to square
that. 

Dirk
