Hello - here is what I am sure is a quick question from someone new to R in
spatial stats. I have a long list of lat long coordinates and I would like
to do a location country check to extrapolate a country name from each
lat/long point.

so, for example, my data look like

lat, long
14.42, -89.92
14.42, -89.75
14.42, -89.58
14.42, -89.42
14.42, -89.25

continued for the terrestrial surface of the earth.

If I want to add country names, so I can use those names as tags to merge in
other data, is there an easy lookup that will allow me to do that, so I end
up with:

lat, long, country
14.42, -89.92, Guatemala
14.42, -89.75, Guatemala
14.42, -89.58, Guatemala
14.42, -89.42, El Salvador
14.42, -89.25, Honduras

Thanks for the help.

Cheers
