So it was simple, or so it seemed. Now to throw a spanner in the works! I got this error when testing it on my more powerful desktop (using one of my lists put in to a new object) : #put list in to new object called "temp" temp<-rg.lmer #save save(temp,file="C:\\Users\\...\\R & Data\\rg.lmer.txt")
It is conventional to save R workspace with ".Rdata" extension rather than ".txt", although I don't think it actually makes a difference.
#remove temp list from workspace to test load rm(temp) #load list in to a new object, again called temp.
temp<-load("C:\\Users\\...\\R & Data\\rg.lmer.txt")
Don't assign the return value of load to an object(). Just do
load("C:\\Users\\...\\R & Data\\rg.lmer.txt")
temp<-load("C:\\Users\\...\\R & Data\\rg.lmer.txt")
Error: cannot allocate vector of size 98 Kb In addition: Warning messages: 1: Reached total allocation of 8148Mb: see help(memory.size) 2: Reached total allocation of 8148Mb: see help(memory.size) The save process takes a very long time but works so I wonder if there is a quicker way to get the same result. The load takes a long time to throw out this error message. Again I hope there is a more efficient way to do it because it defeats the point of saving it in the first place if it takes as long as running the original script to make the list! Also it means I haven't been able to check if the load works and will produce the desired list. *Summary: Is there a better way than save / load, if not how can I get around this error message?*
Maybe, but I would start be trying again, starting from a clean R session (either restart of run rm(list=ls()) to delete everything in your workspace), and properly using load() as I illustrated above. If you still have memory problems then you can start looking for another solution. Best, Ista
