In lgsilvaesilva/spGoogle: Interacting R with Google maps: Spatial visualization tool

Description

Export to GoogleMaps R spatial data information

Usage

spGplot(data, var = NULL, maptype = "satellite", description = list(var =
  NULL, type = NULL, title = NULL), decimals = 3, col.pallete = list(col =
  heat.colors(if (length(cuts) == 1) cuts else length(cuts)), alpha = 1),
  legend.att = list(title = NULL, ncol = 1, bg = "#FFFFFF"), cuts = 5,
  cuts.type = "range", lwd = 1.5, sizeBall = c(0.5, 1), savekml = NULL,
  map.name = "kml", map.description = "description", google.maps = TRUE,
  google.earth.path = try(system("which google-earth", ignore.stdout = T,
  ignore.stderr = T), silent = T), ...)

Arguments

data	a spatial data from any sp classes.
var	an attribute name in the spatial data.
maptype	GoogleMaps types: 'satellite', 'terrain', 'roadmap', 'satellite', 'hybrid'.
description	a list containing the description information in the balloon. var = attribute name(s) in the spatial data. type = type of plot inside the balloon: 'table', 'bar', 'pie' and 'png'. title = balloon title.
decimals	number of decimals in the legend.
col.pallete	a list containing the pallete of colors to be used (col) and the transparency level (alpha) .
legend.att	a list containing the attributes for legend. See legend.
cuts	number of cuts in the legend. Can also be a vector with the cuts point.
cuts.type	method of selecting the cuts points. Ignored if cuts = vector .
lwd	the line width for SpatialLines/SpatialLinesDataframe class.
sizeBall	numeric vector of the length 2 providing the min and max of the balls.
savekml	the name of the output KML. If name is not defined the function will create the file in directory temporary. Default is NULL.
map.name	the name of the KML.
map.description	the description of th KML.
google.maps	boolean. Default TRUE. Define if the data should be exported to GoogleMaps.
google.earth.path	if google.maps = FALSE then GoogleEarth path must be provided
...	further arguments passed to or from other methods.

Value

A plot window on the browser.
