geocoding

问题 I am attempting to utilize the Census Bureau's batch geocoder (http://geocoding.geo.census.gov/geocoder/Geocoding_Services_API.pdf) with R. The input addresses are in a data frame, not a CSV. As the addresses are an intermediate step, I do not want to write them to a CSV. I have read several postings on stackoverflow. Hadley's solution (Posting to and Receiving data from API using httr in R) illustrates how to upload an existing CSV file. MrFlick's solution (Uploading a csv to an api in R)

In GMap v3 oder v2. Maybe bing maps or Open Street Map is better? 回答1: Is there any way I can speed this up? No. The rate limit and quota is there to prevent you from abusing the service. It is possible that a paid license might give you a higher limit (but I don't think so). Without saving the lat/long
