[R-sig-Geo] Getting started with RGeo

[Danlin Yu]

John:

Depending on what datasets you have and what type of analysis you'll 
most likely to conduct, there are many choices.

Personally, I started almost the same as you around 4 years ago, and 
choose SPDEP as my get-in package. Why not take a look at?

Good luck.

Best,
Danlin
