[R-sig-Geo] How to get the coordinates (latitude/longitude) of a continent outline?

[Sohrab Abbasnejad]

 Dear Ben,

Thank you for your reply.

So far as I am aware, the rnaturalearth package provides information about countries within a continent, states within countries and "world" coastline (subsetting the coastline is not possible). Nevertheless, the package does not include maps/data of "continents". What I need is the coordinates of Africa's outline (as a single entity), not the coordinates of countries' outlines within Africa.

Best,
Sohrab

 Hi,
There is a whole world of options (sorry for the lame pun!), but I would recommend checking out ROpenSci's rnaturalearth package

Hello,
I would like to have the list of coordinates of the boundary (outline) of a continent (Africa). The "map" function from the "maps" package gives the coordinates for country outlines, but not the for the continents.

Does anybody have an idea where I can find the data?

Thank you!

Cheers,
Sohrab
