glm gamma scale parameter
...elp & search the archives but I'm a bit confused trying
to reconcile the terminology I'm used to w/R terminology as we're
transitioning to R, so if I missed an obvious way to do this, or stated
this question in a way that's incomprehensible, my apologies.

Can we do GLM on 2GB data set with R?
...eem to find a way to tell what the boundaries
are & roughly gauge the needed memory...other than trial & error. I've
started by testing the data.frame & run out of memory on my PC. I'm new
to R so please be forgiving if this is a poorly-worded question.

turning off automatic coersion from list to matrix
Hello,
I am having trouble understanding how R is coercing between matrices and
lists in the following example. I have an aggregate behavior I like:
aggregate(a[,"num"],by=list(product=a[,"product"],region=a[,"region"]),
sum)

flat text files. The 100% sample is about 350MB. When I read the 1%
and 10% files, besides being slow, everything works. RAM footprint
appears to increase approximately 2x of text
