Dear R Group Users: If there is a resource or easy way to calculate the distance between zipcodes, for example, if I have the zipcode for 200 patients, and the zipcode of a hospital, how to calculate the travel distance of these individual patient to the hospital based on the zipcode. Your input will be greatly appreciated.
Thanks and regards, XING ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
