如何使用R计算以英里为单位的两个邮政编码之间的距离

Question

I wanted to calculate the distance between two zip codes. Is there any particular function to find the distance?

I used this code

Dataframe <- transform(dataframe, Distance = ifelse(a == "" | b == "", "", georoute( c("a", "b"), verbose=TRUE, returntype="distance", service="bing" )))

Where a and b are two separate columns which contain zipcodes of two different areas.

I used the code given at Determing the distance between two ZIP codes (alternatives to mapdist)

Answer 1

You can find online a table that has longitudes and latitudes for 29,000+ US cities, along with their zip codes. with it you could then convert your columns of zip codes to coordinates.

Then, the geosphere package offers eight functions for calculating distances (great circle, Haversine, Rhumb, etc) based on coordinates. It also converts meters to miles.
