addIcon: Add Icons to a Map or RgoogleMap Plot

In PWFSLSmoke: Utilities for Working with Air Quality Monitoring Data

Description

Adds an icon to map – an RgoogleMaps map object. The following icons are available:

• orangeFlame – yellow-orange flame

• redFlame – orange-red flame

You can use other .png files as icons by passing an absolute path as the icon argument.

Usage

addIcon(icon, longitude, latitude, map = NULL, expansion = 0.1, pos = 0)

Arguments

icon	object to be plotted
longitude	vector of longitudes
latitude	vector of latitudes
map	optional RgoogleMaps map object
expansion	icon expansion factor
pos	position of icon relative to location (0=center, 1=bottom, 2=left, 3=top,4=right)

Note

For RgoogleMaps, the expansion will be ~ 0.1 while for basic plots it may need to be much smaller, perhaps ~ 0.001.

Examples
