Sorry for the post. My mistake. The further investigation shows that .Call()
passes arrays/vectors by reference.

I need to pass a large array to my C function. I am using .Call(). I can
clearly see according to the memory consumption (reported by gc()) that the
array is duplicated. Is there a way to avoid this duplication and pass the
array by reference?

You could look at some extension packages, bigmemory for example. A recent
paper http://www.jstatsoft.org/v55/i14 (though for more developer-level
capabilities you would need to look at the package itself
My machine has hundreds of GB of RAM. Is there a way to create an array having
more than 2 Billion (2^31) rows?
I am trying to create a large array using:
d = c(1e+10,2)
a=array(0,d)
This results in the error:
Error in array(0, d) : negative length vectors are not allowed

I need to create a data.frame from C-language and populate it. I Know how to
create lists from C, but I cannot figure out how to create a data.frame. Does
anyone have a sample code for creating a data.frame, setting column names, and
populating it with data?
Thanks!
