The pal addin allows users to interactively select a pal to
interface with the current selection. This function is not
intended to be interfaced with in regular usage of the package.
To launch the pal addin in RStudio, navigate to Addins > Pal
and/or register the addin with a shortcut via
Tools > Modify Keyboard Shortcuts > Search "Pal"—we suggest Ctrl+Alt+P
(or Ctrl+Cmd+P on macOS).
