Add a Custom Editor Theme

Adds a custom editor theme to RStudio and returns the name of the newly added theme.

addTheme(themePath, apply = FALSE, force = FALSE, globally = FALSE)

Arguments

themePath	A full or relative path or URL to an `rstheme` or `tmtheme` to be added.
apply	Whether to immediately apply the newly added theme. Setting this to `TRUE` has the same impact as running `{ rstudioapi::addTheme(<themePath>); rstudioapi::applyTheme(<themeName>) }`. Default: `FALSE`.
force	Whether to force the operation and overwrite an existing file with the same name. Default: `FALSE`.
globally	Whether to install this theme for the current user or all users. If set to `TRUE` this will attempt to install the theme for all users, which may require administrator privileges. Default: `FALSE`.

The addTheme function was introduced in RStudio 1.2.879.
