Greetings,
I attempted some of the Whatif commands in R and they subsequently
crashed my R session. The R program seems to kill the session after
letting the code run for about an hour. My model had about 15,000
observations and about 15 variables and interactions. Does anyone
have any intuition as to why this is occuring and has anyone run
Whatif successfully? In addition, I attempted to use the "by" command
in my Zelig models and got an error message informing me that I cannot
create a vector of size 121 kb. Has anyone encountered this error,
and does anyone have a suggestion of how to proceed?
Regards,
Sheldon

Hi Sheldon,
It looks like you might have a memory size issue - but you should be able
to handle vectors of that size. Have you reset your defaults of late?
You can use the memory.size() and memory.limit() commands to
check/increase your limits.
Best,
Ian

Sheldon,
you could also try removing objects in
R's memory that you not longer need
(using rm()) and then initiating a
garbage collection (gc()).
