Has anyone successfully used R to access netCDF files larger than 2Gb under Windows?
With the version of the ncdf package that Brian Ripley provides for CRAN extras I get an assertion failure with a 12Gb file, but not a 1Gb subset of it. The same 12Gb file is ok with ncdf on Mac OS X (32bit R) and on Linux(64bit R).

The netcdf code is rather silly: it uses 64-bit versions of seek etc when building a DLL, not on Windows. I can rebuild it using 64-bit seek, but could you please send me (privately) a test case?
