    label = FALSE, pal = "Spectral", ...)

Arguments

map	raster to be saved or displayed
outname	name of the file where the map is saved (without extension).
outext	extension of the created map. If outext = "show", the map is displayed in the R graphics console. Choose between "jpg", "png" or "pdf" to save the map in the corresponding format. By default, outext = "show".
title	title of the map. By default, title="".
shapefile	name of the shape/kml file with objects (points or polygons) to be displayed on the maps. For a shapefile called ‘name.shp’ , shapefile="name". For a kml file, write the name of the layer. If shapefile=NULL, no object will be added to the map. By default, shapefile=NULL.
shapedir	path to the shape/kml file. For a shapefile, shapedir is the path to the folder containing the shapefile. For example if the directory of the shapefile is ‘C:/Dir/name.shp’, shapefile="C:/Dir/". For a kml file, shapedir is the full directory of the kml file. For example shapefile="C:/Dir/name.kml". If shapedir=NULL, no object will be added to the map. By default, shapedir=NULL. Please note that paths to files in R can be specified with either "/" or "\\" in Windows OS and "/" in UNIX OS.
shapeext	extension of the shape/kml file : "shp" for a Esri shapefile or "kml" for a kml file from Google earth . By default, shapeext = "shp".
label	name of the label of the points to be displayed on the map. For a shapefile, please indicates the name of the category you want to see. For a kml file, label="Name". If label=FALSE, no label will be plotted. By default, label=FALSE.
pal	name of the palette of colors used to make the map from the package RColorBrewer. To see the different palettes available for your map, please type display.brewer.all(). By default, pal="Spectral".
