Dear R users,
I have a list of objects of type "im" 
> mylist$sp1
$sp2
$sp3

and I want to convert them to a list of objects of class "SpatialGridDataFrame"
This works for a single object of class "im":
a <- mylist$sp1
b <- as(a, "SpatialGridDataFrame")

Then I want to write each element in the new list as a TIFF file, with the name of the elements in the list.
This also works for a single object in package "rgdal":
writeGDAL(b, "sp1.TIFF")

Many thanks,


Robin
