Dear all,

I write to ask whether it is possible to show using R, species distribution
ranges for some plant species occurring in South Africa.

Firstly, I would like to divide the country which they occur into grids or
cells say of 1km square each.

Then assign a name or number to each grid/cell and using presence/absence
(1 or 0), code the distribution of each species.

The idea is to eventually plot the map to show the diversity or
concentration of the species in relation to the country.

Thank you very much

Barnabas Daru
