The instructions here: Dash for R User Guide and Documentation | R & RStats | Plotly do not seem to lead to a correctly deployed app on Heroku.
For instance,
- Following instructions and deploying lead to an error that the version/language of the app cannot be detected
- there is no mention of build packs for R. Is this required? Which one is recommended? I have tried GitHub - virtualstaticvoid/heroku-buildpack-r: Heroku buildpack for R - Makes deploying R on Heroku easy since it seems to be the most popular, but there are errors on deployment:
Error: Failed to install 'dash' from GitHub:
(converted from warning) installation of package ‘/tmp/Rtmpd6Qpbf/file30b4784b2bc/dash_0.1.0.tar.gz’ had non-zero exit status
Execution halted
ERROR: R 3.4.4 failed while executing "init". Check the log for details.
! Push rejected, failed to compile R Console app.
! Push failed
The python instructions work fine, but the R deployment instructions are incomplete.
