Labelling a fortified GADM map plotted with ggplot and geom_map
...Alberta Alberta.1 132
-110.35103 60.00006 3 FALSE 1 Alberta Alberta.1 132
and the data set "tract" is the map data without the "Number" variable.
I looked into working this out from by researching the geom_map function here: http://ggplot2.tidyverse.org/reference/geom_map.html
my code looks like this:
# get the raw map data
can_map <- getData('GADM', country = "CAN", level = 1) # download map level with provinces
tract <- fortify(can_map, region = "NAME_1") # transforms...

NEW FEATURES
* `annotation_custom`: a new geom intended for use as static annnotations that
are the same in every panel. Can be used to add inset plots, tables, and
other grid-based decorations inside the plot area (Contributed by Baptiste
Augui?).
* `geom_map`: a new special case of `geom_polygon` useful when you are drawing
maps, particularly choropleth maps. It is matched with `annotation_map`, an
even faster special case when you want the same map drawn in each panel.
* `geom_raster` is a special case of `geom_tile` for equally sized rectangular...
