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.
