What stopped you re-accessing it?  I would use

save(data.out, file="/home/jenny/data/data.out.RData")
....
load("/home/jenny/data/data.out.RData")

If that does not work, we need to see the transcript to (perhaps) 
understand why (and all the usual details about your environment: it is 
possible to save really large objects that you cannot restore on a 
32-bit machine).
