Subject: bigglm Memory Issues
Hi all,
I'm somewhat of a novice in terms of programming, so I thought I'd come here to
seek some help with an issue I'm having.
[[elided Yahoo spam]]
Here is the particular line of code that is giving me trouble:
>mod = bigglm(Pres/wt ~ Xdes, data=dat, family=poisson(), weights = ~wt,
>maxit=100, tol=1.e-10, chunksize=(dim(Xdes)[1] + 1))
When I attempt to run this, it gives me the following error:
>Error: cannot allocate vector of size 255.9 Mb
However, I had set the maximum memory to 4095 Mb and had used only 926 Mb to
that point.
If I try to use a smaller chunksize, I get this error:
>Error in model.frame.default(tt, chunk) : variable lengths differ (found for
>'Xdes')
Can anybody help me with this?
Thanks,
Ian
