I have the following raster:

myRaster <- c(-176.5813, 174.1103, -31.16667, 83.1)
myRasterExtent <- extent(matrix(myRaster, ncol=2, nrow=2, byrow=T))
myRasterExtent <-  raster(myRasterExtent, crs="+proj=longlat +ellps=WGS84
+datum=WGS84²)

How can I change resolution to 100km^2 and 1000km^2

many thanks
Ross
