Google Maps最短距离

Question

I have a dataset with start (X) and end (Y) coordinates. I want to extract the shortest distance from X to Y using Google Maps. Is there any package/function I can use to do this in R?

Thanks,

@Dave2e is right. use the function mapdist() from library(ggmap) . It has also an argument to set the type of distance to compute (see function argument mode = c("driving", "walking", "bicycling") ). Remember that google maps api limits to 2500 element queries a day.
