Reading in TIFF stacks #9

I have a 4gb tiff video/stack. When I try to use read.image I end up with 20gb of RAM usage which are then interrupted by:

Error: cannot allocate vector of size 15.1 Gb

While the 15Gb might be a limitation that can be fixed somewhere else, why does a 4Gb file need 20Gb of memory?

Are you sure the 4gb stack is not compressed in any way?
