plotOrnithoPoints: Add Observations to Basemap

In heibl/rornitho: Functions for Visualisation of Ornitho Bird Observations

Description

Draw localities of bird observations onto a basemap produced by plotOrnithoMap.

Usage

plotOrnithoPoints(x, show.hidden = FALSE, col, 
    grid, gridcol = "grey25",cex, ...)

Arguments

x	an object of class ornithoSpec.
show.hidden	logical, indicating if restricted ("hidden") data should be shown, defaults to FALSE.
grid	an object of class SpatialPolygonsDataFrame containing the grid that defined the resolution of the raster.
gridcol	a character string giving the color of the grid for plotting; setting gridcol = NA suppresses the plotting of the grid.
col	a nine-level color palette, the second and eighth levels are used to color non-breeding and breeding code observations, respectively.
cex	numeric, giving the size of points to be plotted, if argument is missing cex size will be abundance weighted.
...	further arguments passed through function points.
