    768), add = FALSE, FUN = points, mar = c(0, 0, 

    0, 0), verbose = 0, ...)

Value

nothing returned

Arguments

mt

list returned by GetMapTiles

lat

latitude values to be overlaid, if any

center

optional center

size

size (in pixels) of "stitched" map

add

  center = c(mean(lat), mean(lon));


  zoom <- min(MaxZoom(range(lat), range(lon)));


  bb=qbbox(lat,lon)
