plotSGMap: Plot data on a static map of Singapore

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

Description

A simple ggmap wrapper which enables users to plot the data retrieved from the LTA APIs on a static map of Singapore. Some simple 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 rename the latitude and longitude columns to 'Latitude' and 'Longitude' respectively.

  darken = 0)

Arguments

dataframe	The dataframe containing the latitude/longitude data
colour	Colour of the markers - default is 'red'
size	Size of the markers - default is 1
alpha	Opacity of the markers - default is 0.5
darken	How dark the base map should be - default is 0
