(max int is VK> 2147483647, max long int is 9223372036854775807) Well, Brian gave you all info: Did you really carefully read ?Memory-limits ?? BTW: The package 'Matrix' has many facilities to work with sparse matrices; and these facilities are used in "lme4" and more than a dozen other CRAN packages to work with sparse matrices in the order of 10^5 x 10^5, sometimes even 10^6 x 10^6, *but* with sparse content.
