Hi everyone. I recently had a request for a map with graticules labeled fully around the map as opposed to the default:
labels.pos : position of the labels. Vector of two: the horizontal ("left" or "right") and the vertical ("top" or "bottom") position.
These are two examples:

  tm_shape(NLD_muni) +
  tm_polygons("pop_65plus") +
  tm_graticules(labels.pos = c("right", "top"))

The default only takes a vector of two so I attempted 4 to see if anything changes but it only took the first two.

  tm_shape(NLD_muni) +
  tm_polygons("pop_65plus") +
  tm_graticules(labels.pos = c("right", "top","left","right"))

Is there a way to have the four sides labeled?
Also the map looks better with left and bottom labels. With the right and top, the right labels are not mirrored but overlap the map frame itself. Is there a fix for this?
Here's the left bottom example:
