Building R Packages in RStudio Package Manager

Follow

R packages can come in multiple formats:

  • Source: A collection of directories and files containing source code.
  • Bundle: A specially created tar file containing bundled source code. The result of R CMD build.
  • Binary: A binary file specific to an operating system and architecture, containing compiled source code. Not an executable. The result of R CMD INSTALL.

In some configurations, RStudio Package Manager will need to run R in order to transform a package from one state to another. RStudio Package Manager uses the RStudio Job Launcher to perform this task.

Currently, the Job Launcher and R installation are only relevant if you use git sources.

Job Launcher

The RStudio Job Launcher is a service responsible for running jobs in support of RStudio Package Manager. The Job Launcher is automatically installed when RStudio Package Manager is installed. Settings for the Job Launcher can be configured directly in the RStudio Package Manager configuration file, /etc/rstudio-pm/rstudio-pm.gcfg, see Appendix A in the admin guide.

RStudio Package Manager can only use its own instance of the Job Launcher and runs all tasks locally. Other RStudio products may have separate Job Launcher instances managed independently from RStudio Package Manager. The RStudio Package Manager’s Job Launcher cannot be shared by other products, nor can RStudio Package Manager use a Job Launcher instance set up for another product.

R Configuration

The Job Launcher requires a valid installation of R. Any version of R greater than 3.0.0 is sufficient. Specify the installation of R in the
RStudio Package Manager configuration file:

; /etc/rstudio-pm/rstudio-pm.gcfg
[Server]
RVersion = /opt/R/R-3.4.1

Replace /opt/R/R-3.4.1 with the path to your R installation. Use the path to the R installation directory, not the path to the binary (do not include /bin/R). While multiple versions of R may be installed on the server, only one version of R may be specified for use by RStudio Package Manager.

The RVersion configuration option and an installation of R is not required, however if the RVersionfield is included it must be valid and must only appear once in the configuration file. Check the server log after starting and stopping for messages relevant to the R configuration.

R Installation

We highly recommend installing R from source. Installing R from source makes it is easy to manage multiple versions of R, prevents accidental upgrades of R, and ensures R is built with your architecture. The RStudio Server documentation contains instructions for building and installing R from source.

This RStudio Support article also includes R installation instructions.
