  Thank you Roman and Johannes,

What I am doing wrong?

x <- readGDAL("bio1_23.bil")
xr = raster(x)

map <- readOGR(dsn="C:/ProyectoRespacial/EvalHab_reporte", 
layer="Cr_wgs84_meso") # shapefile

 > r2 <- polygonsToRaster(map, xr)
Found 1 region(s) and 1 polygon(s)
Error: no se puede ubicar un vector de tamaño  98.9 Mb

Best,

Manuel
