RStudio user preferences for your runs (such as theme) are stored in a file in /home/ubuntu/.rstudio/monitored/user-settings/user-settings. To launch RStudio with custom preferences, you can use the pre-setup script in a custom compute environment to modify this file.

Method 1: Write lines to settings file

If you know what to add to the settings file, you can write it in the pre-setup script. For example:

mkdir -p /home/ubuntu/.rstudio/monitored/user-settings/ <b class="conum">(1)</b>
echo 'uiPrefs={"theme" : "Mono Industrial"}' >> /home/ubuntu/ .rstudio/monitored/user-settings/user-settings <b class="conum">(2)</b>
chown -R ubuntu:ubuntu /home/ubuntu/.rstudio <b class="conum">(3)</b>
if [ -f .domino/launch-rstudio-server ]; then
    sed -i.bak 's# > ~/.rstudio/monitored/user-settings/user-settings# >> ~/.rstudio/monitored/user-settings/user-settings#' .domino/launch-rstudio-server <b class="conum">(4)</b>
    chown ubuntu:ubuntu .domino/launch-rstudio-server <b class="conum">(3)</b>
fi

The following describes what each line is doing:

The mkdir statement creates the encompassing directory.
The echo statement writes the theme to the file. If you prefer to store a file in your project, you can replace this with a copy operation (see the next method).
The chown statements avoid a permissions error.
The sed statement modifies a Domino script that would overwrite this settings file.

Method 2: Copy a saved settings file

Use this method if do not know what lines to add, or if you want to persist this settings file in your project.

Run a session and modify the RStudio preferences as needed.
Before you stop the session, use the following R code to copy the user-settings file to the root of your project directory.
```
file.copy("/home/ubuntu/.rstudio/monitored/user-settings/user-settings", ".")
```

Add the following lines to the pre-setup script of your environment definition to load the preferences file (if it exists) on subsequent runs:

if [ -f user-settings ]; then
    mkdir -p /home/ubuntu/.rstudio/monitored/user-settings/
    cp user-settings /home/ubuntu/.rstudio/monitored/user-settings
    sed -i.bak '/initialWorkingDirectory=/d' /home/ubuntu/.rstudio/monitored/user-settings/user-settings
    chown -R ubuntu:ubuntu /home/ubuntu/.rstudio
    if [ -f .domino/launch-rstudio-server ]; then
        sed -i.bak 's# > ~/.rstudio/monitored/user-settings/user-settings# >> ~/.rstudio/monitored/user-settings/user-settings#' .domino/launch-rstudio-server
        chown ubuntu:ubuntu .domino/launch-rstudio-server
    fi
fi
