Install
A note about installing rgeos - built on top of C libraries, and installation often causes trouble for Linux users because no binaries are provided on CRAN for those platforms. Other dependencies in geojsonio should install easily automatically when you install geojsonio.
Mac
Install GDAL on the command line first, e.g., using homebrew
brew install gdal
Then install rgeos
install.packages("rgeos", type = "source")
Linux
Get deps first
sudo apt-get install libgdal1-dev libgdal-dev libgeos-c1 libproj-dev
Note: if you have trouble installing rgeos, try installing
libgeos++-dev
Then install rgeos
install.packages("rgeos", type = "source")
