plot_gmap: Plot Google Earth images obtained through dismo::gmap

In Pakillo/rSDM: Species distribution and niche modelling in R

Description

This function is very slightly modified from .plotCT function in raster package to avoid producing an empty plot before the actual Google image.

Usage

plot_gmap(
  x,
  maxpixels = 5e+05,
  ext = NULL,
  interpolate = FALSE,
  axes,
  main,
  xlab = "",
  ylab = "",
  asp,
  add = FALSE,
  addfun = NULL,
  zlim = NULL,
  zlimcol = NULL,
  ...
)

Arguments

x	RasterLayer, as obtained through gmap.
maxpixels	integer > 0. Maximum number of cells to use for the plot. If maxpixels < ncell(x), sampleRegular is used before plotting. If gridded=TRUE maxpixels may be ignored to get a larger sample.
ext	An extent object to zoom in a region
interpolate	Logical. Should the image be interpolated (smoothed)?
axes	not used
main	character. Main plot title
xlab	Optional. x-axis label
ylab	Optional. y-axis label
asp	not used
add	Logical. Add to current plot?
addfun	Function to add additional items such as points or polygons to the plot (map). Typically containing statements like "points(xy); plot(polygons, add=TRUE)". This is particularly useful to add something to each map when plotting a multi-layer Raster* object.
zlim	not used
zlimcol	not used
...	Graphical parameters. Any argument that can be passed to rasterImage.

Value

A plot.
