GeoCodes text locations using the GeoNames API

Description

Uses the location_word and Country columns of the data frame to make queries to the geonames API and geocode the locations in the dataset.

1. The Geonames API (for free accounts) limits you to 1000 queries an hour

2. You need a geonames username to make queries. You can learn more about that here

Arguments

.	a data frame which has been locationized (see weed::split_locations)
n_results	number of lat/longs to get
unwrap	if true, returns lat1, lat2, lng1, lng2 etc. as different columns, otherwise one lat column and 1 lng column
geonames_username	Username for geonames API. More about getting one is in the note above.

Value

the same data frame with a lat column/columns and lng column/columns

Examples

df <- tibble::tribble(
   ~value,  ~location_word,                    ~Country,
   "mumbai region, district of seattle, sichuan province",  "mumbai","India",
   "mumbai region, district of seattle, sichuan province",  "seattle", "USA"
