PlotArrowsOnStaticMap: plots arrows or segments on map

In RgoogleMaps: Overlays on Static Maps

plots arrows or segments on map

Description

This function plots/overlays arrows or segments on a map.

Usage

PlotArrowsOnStaticMap(MyMap, lat0, lon0, lat1 = lat0, 


    lon1 = lon0, TrueProj = TRUE, FUN = arrows, add = FALSE, 


    verbose = 0, ...)

Arguments

MyMap	map image returned from e.g. GetMap()
lat0	latitude valuesof points FROM which to draw.
lon0	longitude values of points FROM which to draw.
lat1	latitude valuesof points TO which to draw.
lon1	longitude values of points TO which to draw.
TrueProj	set to FALSE if you are willing to accept some degree of inaccuracy in the mapping. In that case, the coordinates of the image are in lat/lon and the user can simply overly points/lines/axis without worrying about projections
FUN	, plotting function to use for overlay; typical choices would be arrows and segments
add	start a new plot or add to an existing
verbose	level of verbosity
...	further arguments to be passed to FUN
