i *SOLVED* Thanks Milan, I have receivd some feedback externally to the list and managed to solve the issue.
I saved the document as follows: x.Arr <- ff(NA, dim=rep(ngen,3), vmode="double") ffsave (x.Arr, file="x.Arr") finalizer(x.Arr) <- "delete" The problem was related to the rootpath argument. As the one in one computer does not exist in the other, the solution was to set it when ffloading, so: ffload(file="/path/to/saved/x.Arr", rootpath = "/path/on/your/other/computer/where/to/extract/x.Arr") Cheers, Djordje 2013/5/26 Milan Bouchet-Valat <nalimi...@club.fr> > Le dimanche 26 mai 2013 à 13:53 +0200, Djordje Bajic a écrit : > > Hi all, > > > > I am having trouble loading a ff object previously saved in a different > > computer.
