[R] Using very large matrix

[Corrado]

Dear friends,

I have to use a very large matrix. Something of the sort of 
matrix(80000,80000,n) .... where n is something numeric of the sort 0.xxxxxx

I have not found a way of doing it. I keep getting the error

Error in matrix(nrow = 80000, ncol = 80000, 0.2) : too many elements specified

Any suggestions? I have searched the mailing list, but to no avail. 

Best,
--
