RgoogleMaps (version 1.2.0.7)

SpatialToPBS: converts spatial objects as defined in package sp to simpler PBSmapping type dataframes

Description

The PlotPolysOnStaticMap() function currently does not take sp objects directly but instead needs

PBSmapping type data.frames. This function converts sp objects into such.

Usage

SpatialToPBS(xy, verbose = 0)

Arguments

xy

spatial object, such as SpatialPoints, SpatialPolygons, etc..

verbose

level of verbosity

Value

Examples

  if (interactive()) {


  data("NYleukemia", envir = environment())


  population <- NYleukemia$data$population


  cases <- NYleukemia$data$cases


  mapNY <- GetMap(center=c(lat=42.67456,lon=-76.00365), 


                  destfile = file.path(tempdir(),"NYstate.png"), 


                  maptype = "mobile", zoom=9)


  #mapNY=ReadMapTile("NYstate.png")


  clrStuff=ColorMap(100*cases/population, alpha = 0.35, log = TRUE)


  NYpolys = SpatialToPBS(NYleukemia$spatial.polygon)


  PlotPolysOnStaticMap(mapNY, NYpolys$xy, col = clrStuff$colcode, add = FALSE)


  legend("topleft", legend = clrStuff$legend, fill = clrStuff$fill, 


         bg = rgb(0.1,0.1,0.1,0.3))
