I would approach this by reading the data in using readOGR from rgdal

package. Once you get your projections in order, I would use one of the

functions in rgeos to find which "cubes" (let's call them squares for the

lack of a better term :) ) lie on the country border.

You can merge() your data from the "overlaid" object with your csv file by

cellnumbers.
