A simple Leaflet wrapper which enables users to plot the data retrieved from the LTA APIs on an interactive map of Singapore. Some basic options are provided for ease of use. Note that this function only works automatically with outputs from getTaxiAvail, getCarparkAvail, getTrafficIncidents, getVMS, and getTrafficImages from this package. For all others, please obtain data for the coordinates and rename the respective columns to 'Latitude' and 'Longitude'.
exploreSGMap(dataframe, popup = NA, cluster = FALSE, colour = "red", size = 5, alpha = 0.5)
