The package and interactive {shiny} app consult several options that you
can easily set via options(). Moreover, there is some behavior that can be
changed through environment variables.
Options are set with options(<option> = <value>).
sia.disable_modules: You can completely disable SIA modules by setting
this to TRUE.
sia.modules_repo: This is the URL for a CRAN-like repository that the app
uses to retrieve information about available module packages.
sia.offer_modules: If set to TRUE (the default), calling run_app()
will check for the available SIA modules at the official repository and offer
to install those module packages that are not installed yet.
You can set this variable system-wide or use R or project-wise .Renviron
file. For more details, please navigate to the R documentation.
SIA_MODULES_DEBUG: Setting this to TRUE provides a verbose description
of SIA modules-related processes. Useful only for debugging purposes.
