Dear all,
having data in a SpatialGridDataFrame with geographic coordinates, is
there a simple method to calculate the spatial area for each cell? I

Thanks and best regards
Tim

with the meuse dataset:
library(sp)
data(meuse.grid)
gridded(meuse.grid) = ~x+y
fullgrid(meuse.grid) = TRUE
bla = gridparameters(meuse.grid)
area = bla$cellsize[1] * bla$cellsize[2]
area
