Map component: mouse coordinates

Map component that adds mouse coordinates

Usage

tm_mouse_coordinates(stack, position, group_id, z)

stack: stack with other map components, either "vertical" or "horizontal".
position: The position specification of the component: an object created with tm_pos_in() or tm_pos_out(). Or, as a shortcut, a vector of two values, specifying the x and y coordinates. The first is "left", "center" or "right" (or upper case, meaning tighter to the map frame), the second "top", "center" or "bottom". Numeric values are also supported, where 0, 0 means left bottom and 1, 1 right top. See also vignette about positioning. In case multiple components should be combined (stacked), use group_id and specify component in tm_comp_group().
group_id: Component group id name. All components (e.g. legends, titles, etc) with the same group_id will be grouped. The specifications of how they are placed (e.g. stacking, margins etc.) are determined in tm_comp_group() where its argument id should correspond to group_id.
z: z index, e.g. the place of the component relative to the other componets
