In PWFSLSmoke: Utilities for Working with Air Quality Monitoring Data

Description

Add a multi-sided polygon to a plot.

Usage

addPolygon(
  x = 0,
  y = 0,
  sides = 72,
  radius = 1,
  rotation = 0,
  border = NULL,
  col = NA,
  ...
)

Arguments

x	x location of center
y	y location of center
sides	number of sides
radius	radius
rotation	amount to rotate the polygon in radians
border	border color (see ?polygon)
col	fill color (see ?polygon)
...	additional arguments to be passed to polygon()

Examples

# Create AQI dots
plot(1:6, rep(0,6), xlim=c(-1,7), ylim=c(-1,3),
    axes=FALSE, xlab='', ylab='', col='transparent')
for (i in 1:6) {
  addPolygon(i, 2, 72, 0.4, 0, col=PWFSLSmoke::AQI$colors[i])
  addPolygon(i, 1, 4, 0.4, pi/4, co=PWFSLSmoke::AQI$colors[i])
  addPolygon(i, 0, 3, 0.4, pi/2, col=PWFSLSmoke::AQI$colors[i])
}
