Yes. The first thing is, use package=ncdf4

http://cran.r-project.org/web/packages/ncdf4/index.html

(rather than the now-unsupported, and deprecated, package=ncdf) and try the example for nc_create in the ncdf4 manual

http://cran.r-project.org/web/packages/ncdf4/ncdf4.pdf

I'm using it for multilayered 459x299 grids (the North American
"AQMEII domain") that are < 1 GB.
