We often need to simplify the geometry of polygons into points or lines. How do you do that in R?

In today’s post, we’ll show you how to use the gDistance function from the rgeos library to calculate the distance

We already know how to download part of an background map from Google Maps. Today we will plot our data

Today we’ll take a look at the ggmap library, which allows us to retrieve a map background from Google Maps

Last time we showed how to give a coordinate system to a loaded vector layer. What if we want to
