Integration with RStudio Cloud
RStudio Cloud is a product geared towards bringing R to everyone. A core
feature of RStudio Cloud is the ability to create projects with as-needed
instances of the standard RStudio IDE, including the ability to publish
content to RStudio Connect. If your users are using RStudio Cloud to
publish content to RStudio Connect, there are some caveats that you should
be aware of:
- RStudio Cloud uses a package proxy replacement for CRAN, which shows up in
the
packrat.lock and manifest.json files as http://package-proxy
- RStudio Cloud supports a fallback repository for its packages which is
listed as
RSPM in the repos R option and points to a CRAN mirror.
- When deployments from RStudio Cloud rebuild on RStudio Connect, users may
see a message saying that it couldn't contact
http://package-proxy
before successfully building.
Suppressing The package-proxy Message
To prevent the package-proxy message from appearing in user deployments,
override CRAN using the
RPackageRepository
configuration heading.
[RPackageRepository "CRAN"]
URL = https://cran.rstudio.com
Making All RStudio Cloud Deployments Restore From RSPM
Because RStudio Cloud uses two repository settings to achieve its fallback
behavior, you will need to override both of them using the
RPackageRepository
configuration heading.
[RPackageRepository "CRAN"]
URL = https://my.package.manager.instance
[RPackageRepository "RSPM"]
URL = https://my.package.manager.instance
Replace https://my.package.manager.instance with the instance of RSPM
you would like to prefer that packages restore from.
