library('rjson') # For parsing json in R
library('RCurl') # For sending an http request
library('plyr')  # For ddply

# Takes an data frame with a unique id column and an address column at the very least
# it returns a data frame with the uid, lat, lng and specificity of geocoding
# use the uid to join these results back to your data if you want
# you can also accomplish roughly the same thing with a for loop instead of ddply
