R: ggmap - Overlay shapefile with filled polygon of regions. You'll learn their syntax and how they work with the help of examples. br reaches roughly 345 users per day and delivers about 10,364 users each month. Because longitude and latitude are angles (they are measured in degrees), they are not considered a "projected" coordinate system (even though your transform worked). This document shows some example R code to do “overlays” and associated spatial data manipulation to accompany Chapter 11 in O’Sullivan and Unwin (2010). If I guess this right, you have coordinates that are in AGD66 so you must first assign that projection and then you can transform. Working with JSON in R can be a bit disorienting because you end up with lists within lists within lists so let's break it down a bit. wgs84 <- spTransform(ldn1, CRS("+init=epsg:4326")) Once this is done it’s easy going from here especially if you are familiar with ggplot2.
