I am using the virtualstaticvoid buildpack for heroku, but it is on the heroku-16 stack and only supports up to version 3.4.4 of R. I am after a buildpack that works on the latest stack (heroku-18) and supports at least version 3.6 of R, and has no outdated dependencies. The hmdc buildpack appears to support heroku-18 and version 3.6.0 of R, but requires packrat which is soft deprecated in favour of renv.
Some good news, virtual_static_void has been updated so the R buildpack
now uses version 4.0.0
, works on both heroku-18
and heroku-16
stacks, and it supports renv
.
