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")
An an identical question from someone with a user name of "rob" was posted to StackOverflow.
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")
