*Make sure you have downloaded the RgoogleMaps package.
** code: library(Rgooglemaps)
* Create a base map
**find geocode for center of desired map, adjust zoom as needed
**example code (for map of North America): newmap <- GetMap(center = c(39, -95), zoom = 3, destfile = "NorthAmerica.png")
*Transform addresses into geocode via http://www.geocodezip.com/v3_example_geo2.asp?addr1=United%20States%20of%20America&geocode=1
*Plot map, adjust variables
** example code: PlotOnStaticMap(newmap, lat = c(30.268606, 41.888519), lon = c(-97.740467, -87.63548), pch = 20, col = "red")
**lat=latitude; lon=longitude, pch = point style, color="color"
Example Code:
Chicago MSA w/ color by Industry
library(RgoogleMaps)
library(ggplot2)
library(colorspace)
library(RColorBrewer)
merged.data<- merge(Chicago.Adresses.for.geocode.v2, Chicago.Addresses.w.Industries, by="Name")
newmap <- GetMap(center = c(41.92,-87.78), zoom = 11,GRAY = TRUE, destfile = "chicago_test.png")
col.list <- c("#EB6D2E","#EB6D2E", "#EB6D2E", "#00B2A9", "#516B66", "#00B2A9")
palette(col.list)
PlotOnStaticMap(newmap, lat=c(Chicago.Adresses.for.geocode.v2$Latitude),lon=c(Chicago.Adresses.for.geocode.v2$Longitude), pch=20, col=c(Chicago.Addresses.w.Industries$Industry))
