Release 1.0 (2010-02-23): Initial release of the ncdf4 package, which provides a high-level R interface to the netcdf library, versions 4 and earlier. Package ncdf4 REPLACES package ncdf, which supplied an interface to version 3 of the netcdf library. Due to changing coding standards requested by CRAN over the years, the NAMES of the functions in ncdf4 are different than the names in ncdf. For example, the function that used to be called "dim.def.ncdf" in ncdf is now called "ncdim_def" in ncdf4.
