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 |
# With the GeoJSON OGR driver one can use the CartoDB SQL API to create any OGR supported format output | |
# OGR Formats: http://gdal.org/ogr/ogr_formats.html | |
# CartoDB SQL API: http://developers.cartodb.com/documentation/sql-api.html | |
# This sample creates a DXF making a "select the_geom from meteo" from my account at CartoDB | |
