plots on map tiles by "stitching" them together
Counterpart to PlotOnStaticMap for map tiles
PlotOnMapTiles(mt, lat, lon, center, size = c(768,
768), add = FALSE, FUN = points, mar = c(0, 0,
0, 0), verbose = 0, ...)mt |
list returned by |
lat |
latitude values to be overlaid, if any |
lon |
longitude values to be overlaid, if any |
center |
optional center |
size |
size (in pixels) of "stitched" map |
add |
start a new plot or add to an existing |
FUN |
plotting function to use for overlay; typical choices would be points and lines |
mar |
outer margin in plot; if you want to see axes, change the default |
verbose |
level of verbosity |
... |
further arguments to be passed to |
