Though it depends on the end goal of what features you are looking for, you can, however find these package useful for that purpose: sp, rgdal, ggmap

In the spatial images - you usually encounter both vector models and raster models. Based on your need and purpose, choose the package that best serves your purpose.

Check out the attached presentation. And do not forget to review: http://cran.r-project.org/web/views/Spatial.html for more details.
