This is a Docker container for R 4.1.0 with RStudio, Intel Math Kernel Library (MKL), and umx package pre-installed.
umx is a package designed to make structural equation modeling easier, from building, to modifying and reporting.
umx includes high-level functions for complex models such as multi-group twin models, as well as graphical model output.
sudo docker pull diffpsych/umx
Map a host folder to the container so the container can access files on host and write out results. This is important since the --rm flag is there to tell the Docker Daemon to clean up the container and remove the file system after the container exits. Make sure you run the container as a non-root user.
sudo docker run -d --rm -v $(pwd):/home/rstudio/data -e USERID=$UID -p 8787:8787 -e PASSWORD=<password> diffpsych/umx
You can then open a web browser pointing to your docker host on port 8787. Username to login to RStudio is rstudio and the password is whatever you set when you ran the container.
