The Outsider is always unhappy, but he is an agent that ensures the happiness for millions of ‘Insiders’.
The Outsider, Wilson, 1956.
Integrating external programs into a deployable, R workflow can be challenging. Although there are many useful functions and packages (e.g.
base::system()) for calling code and software from alternative languages, these approaches require users to independently install dependant software and may not work across platforms.
outsider aims to make this easier by allowing users to install, run and control programs outside of R across all operating systems.

Additionally, you will also need to install Docker desktop. To install Docker visit the Docker website and follow the instructions for your operating system: Install Docker.

outsider makes use of the program docker which allows users to create small, deployable virtual machines, called Docker images. The advantage of these images is that they can be run on any machine that has Docker installed, regardless of operating system. The
outsider package makes external programs available in R by facilitating the interaction between Docker and the R console through outsider modules. These modules consist of two parts: a Dockerfile that describes the Docker image that contains the external program and an R package for interacting with the Docker image. Upon installing and running a module through
outsider, a Docker image is launched and the R code of the module is used to interact with the external program. Anyone can create a module. They are hosted on GitHub as well as other code-sharing sites and can be searched for and downloaded through
