roxygen2::roxygenise(".")
Adds a set_map_alpha() function which appends an alpha channel onto a map. This allows superimposing maps with transparency.
set_map_alpha()
I've included a simple test too.
For example (maps from the examples included with the function):
A 100% opaque map of London
Another 100% opaque map of London
The second map superimposed with 25% opacity
The function documentation includes the code required to produce the above maps.
