Zoom in on a map (plot) by providing a new extent, by default this is done by clicking twice on the map.
zoom(x, ...)
# S4 method for Raster
zoom(x, ext=drawExtent(), maxpixels=100000, layer=1, new=TRUE, useRaster=TRUE, ...)# S4 method for Spatial
zoom(x, ext=drawExtent(), new=TRUE, ...)
# S4 method for missing
zoom(x, ext=drawExtent(), new=TRUE, ...)
Raster* or Spatial* (vector type) object

Maximum number of pixels used for the map
Positive integer to select the layer to be used if x is a mutilayer Raster object
Logical. If TRUE, the zoomed in map will appear on a new device (window)
