Hello all, I hate to add to the daily queries regarding R's handling of large datsets ;), but...
I read in an online powerpoint about the ff package something about the "length of an ff object" needing to be smaller than .Machine$integer.max. Does anyone know if this means that the # of elements in an ff object must be < .Machine$integer.max [i.e., that ff provides no help with respect to the number of elements in a given object]? I've got a matrix that has 19e9 elements and - even though I can fit it into my ram (using "raw" storage.mode) - R won't let me store it because 19e9 is >> .Machine$integer.max = 2^31. Anyone else have suggestions on how to deal with such massive datasets like the ones I'm using? I'm exploring ncdf as we speak. Best, Matt -- Matthew C Keller Asst.
