Arguments

data: An sf object of geometry type point/multipoint, linestring/multilinestring or polygon/multipolygon geometry type. Required input.
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.
popup_numeric_format: A function to format all numeric variables within the popup column. Defaults to non-scientific. Use function(x) x to leave as is.
popup_vars_rename: Function to rename column names for the popup. Defaults to snakecase::to_sentence_case. Use function(x) x to leave column names untransformed.
pal: Character vector of hex codes.
size_point: Size of points (i.e. radius). Defaults to 2.
size_line: Size of lines around features (i.e. weight). Defaults to 2.
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.
layer_id_var: Unquoted variable to be used in shiny, so that in the event where a feature is clicked on, the value of this is returned for that feature (e.g. input$map_marker_click$id).
group_id: The id name for the sf group.
map_id: The map id for the leaflet map. Defaults to "leaf".
