popup	TRUE or FALSE of whether to have a popup.
popup_vars_vctr	Vector of quoted variable names to include in the popup. If NULL, defaults to making a leafpop::popupTable of all columns.

alpha_point	The opacity of the points.
alpha_line	The opacity of the outline.
alpha_fill	The opacity of the fill.
basemap	The underlying basemap. Either "light", "dark", "satellite", "street", or "ocean". Defaults to "light". Only applicable where shiny equals FALSE.

group_id	The id name for the sf group.
map_id	The map id for the leaflet map. Defaults to "leaf".
