I have a list of latitude and longitude coordinates, and wish to find out which country they all reside in.

I modified an answer from this question about lat-long to

Answer 1

You can use my geonames package to lookup from the http://geonames.org/ service:

> GNcountryCode(51.5,0)
$languages
[1] "en-GB,cy-GB,gd"

$distance
[1] "0"

$countryName
[1] "United Kingdom of Great Britain and Northern Ireland"

$countryCode
[1] "GB"

> GNcountryCode(44.5,20)
$languages
[1] "sr,hu,bs,rom"

$distance
[1] "0"

$countryName
[1] "Serbia"

$countryCode
[1] "RS"

Get it from r-forge because I'm not sure I bothered to release it to CRAN:

Yes, it depends on an external service, but at least it knows what happened to communism... :)
