Add Drawing

Adds drawing tools to the map. Particularly useful when in an interactive (shiny) environment.

add_drawing(map, drawing_modes = c("marker", "circle", "polygon",
  "polyline", "rectangle"), delete_on_change = FALSE)

Arguments

map

a googleway map object created from google_map()
drawing_modes

string vector giving the drawing controls required. One of one or more of marker, circle, polygon, polyline and rectangle
delete_on_change

logical indicating if the currently drawn shapes should be deleted when a new drawing mode is selected (only works in a reactive environment)

Examples

# NOT RUN {
map_key <- 'your_api_key'
google_map(key = map_key) %>%
  add_drawing()

# }
