The package ncdf4  (http://cran.r-project.org/web/packages/ncdf4/index.html) can access remote OpeNDAP data services.  If you use Windows, the author has a binary package on his site.

Also, if you want a GUI that works with R and allows you to visually select the space-time slice you want, try the Environmental Data Connector for R (http://www.pfeg.noaa.gov/products/EDC/EDCdownloads.html)
