R - How to convert latitude and longitude coordinates into an address/ human readable location?

Question

How can I convert latitude and longitude coordinates into an address/ human readable location in R?

For instance I have these data below:

humandate           lat         lon     
09/10/2014 13:41    41.83174254 -75.87998774    
09/10/2014 13:53    41.83189873 -75.87994957

I want find out what the address/ location is for latitude 41.83174254, longitude -75.87998774. Is it possible with R? or with something else?

I think this is probably best asked on GIS SE. I don't know of a package in R that obtains addresses from coordinates, but there might be a way to use R to interface to a database that does have this information. — Phil, Apr 28 '15 at 14:04

Use the revgeocode function from the ggmap package. Using your data.frame df:

revgeocode(c(df$lon[1], df$lat[1]))

"27-37 Beech Street, Montrose, PA 18801, USA"

You could create a new variable in your data.frame with these values:

df$textAddress <- mapply(FUN = function(lon, lat) revgeocode(c(lon, lat)), df$lon, df$lat)
