          **WARNING** A newer version of r is available in this buildpack. Please adjust your app to use version 3.5.3 instead of version 3.5.2 as soon as possible. Old versions of r are only provided to assist in migrating to newer versions.
          **WARNING** r 3.5.x will no longer be available in new buildpacks released after 2019-03-11.

For me, the buildpack is unable to reach the local CRAN repository: http://s0hrep0001h.cbsp.nl/cran. Are you facing the same issue? Please provide some of the log output from running cf push so that we can better diagnose the problem.

Also consider looking at the "Vendoring App Dependencies" section of the Cloud Foundry R Buildpack Documentation for a way of creating local CRAN-like repo.

@floragj It looks like that cran_mirror in the attached application is behind firewall. I was able to reproduce this issue by changing the cran_mirror to https://cran.r-project.org.

@rwaaijman - you can use tidyverse in your application by using the Apt Buildpack along with the R Buildpack. Per the instructions here, you can define an apt.yml file, and modify your manifest.yml to push with both the Apt Buildpack and the R Buildpack. Note that Shiny is already provided by the buildpack, so it's not necessary to install in your r.yml.

apt.yml

---
truncatesources: true
cleancache: true
packages:
- libcurl4-openssl-dev
- libssl-dev
- libxml2-dev

manifest.yml

---
version: 1
applications:
- name: simpel		#naam app
  memory: 2G			#geheugen
  instances: 1			
  random-route: false
  buildpacks:
  - apt_buildpack 		#installeren extra linux aps
  - r_buildpack			#installeren r en libraries
  command: R -f app.R		#starten R app

We will be making it easier to install additional packages in the next generation of the R Buildpack, the R Paketo Buildpack. Closing for now, but feel free to open back up if you run into any other issues.
