spatialChoropleth: lifted from choropleth in the USCensus2000 package

In DeducerSpatial: Deducer for spatial data analysis

Description

produces a choropleth plot for a SpatialPolygonsDataFrame

Usage

spatialChoropleth(sp, color ,quantileBin=FALSE, palette, alpha=1,
		main = NULL, sub = "", legend.loc = "bottomleft", 
		legend.title ,add=TRUE,border="transparent", ...) 

Arguments

sp	a SpatialPolygonsDataFrame
color	the variable to map to color (either the name in x or a vector)
quantileBin	should color be devided into quantile bins. If true, 5 bins are useds. alternatively quantileBin can be set to the number of desired bins
palette	A color scale (See the scales package)
alpha	transparency
main	title
sub	subtitle
legend.loc	legend location
legend.title	title
add	add to current plot
border	polygon border type
...	additional parameters for plot

Examples

## Not run: 
library(UScensus2000)

lat <- c(43.834526782236814,30.334953881988564)
lon <- c(-131.0888671875  ,-107.8857421875)
southwest <- openmap(c(lat[1],lon[1]),c(lat[2],lon[2]),5,'bing')
data(california.tract)
california.tract <- spTransform(california.tract,osm())

plot(southwest,removeMargin=TRUE)
spatialChoropleth(california.tract,'med.age',
		legend.title = 'Median Age',alpha=1)
