exploreSGMap: Explore data on an interactive map of Singapore

In shaunkhoo/ltaer: R Package for LTA's APIs

Description

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.

For all others, please obtain data for the coordinates and rename the respective columns to 'Latitude' and 'Longitude'.
