[R] Cannot allocate vector of size x

[Rubén Roa]

Yes, on a recent heavy-duty job -profile likelihood of Tweedie power parameter for a relatively complex glm with hundreds of thousands rows dataframe- I had the "cannot allocate vector ..." error, then I just closed-saved the main workspace, full of large objects, then I did the profiling on a fresh and almost empty (with strictly necessary objects) workspace, and it run successfully. Then I just loaded the two workspaces to one session,  and continued happily to the end of the job. :-)

how much memory do you have on your system? How large are the vectors you are creating? How many other large vectors do you have in memory?  Remove all unused objects and do gc() to reclaim some of the memory. Remember all objects are in memory and you have to understand how large they are and how many you have. Ther is more information you have to provide and some more inspection you have to do.
