Perhaps you can start posting your problem in this list with a more detailed
explanation of the R's version you have, platform you use, and very
important in the e-mail subject.

Regarding the memory, its limit has been extended in the 1.6.0/1.6.1
versions.

Also, perhaps betwen putting your data in a data.frame (I presume) and the
moment you generate your linear model, you have variables that are using
momory space unnecessary, try to remove them.

Finally, rather than using the entire data set, you can start doing some
exploratory analysis with a sample of your population.
Check sample() for that.

Regards,
Carlos.

Dear all:

I am another R-beginner in the state.

I have tried to analyze a large data (3,600 kb as csv format) set with R.
When I type lm(x~y), it says

> ====
> Error: cannot allocate vector of size 1017272 kb.
> In addition: Warning message:
> Reached total allocation of 255MB: see help(memory.size)
> ====
> So, I tried the following.
> >memory.size()
> [1] 51620896
> >memory.limit()
> [1] 267878400
> >melory.limit(1200)
> NULL
> Error: cannot allocate vector of size 1017272kb.
>

Does any of you have any idea how can I solve this problem?
Sorry for bothering you during Holiday.

Thanks,

Chris
