Map component: mouse coordinates

Map component that adds mouse coordinates

Usage

tm_mouse_coordinates(stack, position, z)

stack: stack with other map components, either "vertical" or "horizontal".
position: 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.
z: z
