I've been using the ncdf package for reading climate data (mostly, NCEP/NCAR and ECMWF reanalysis stuff). The package does what it says on the tin, but can become quite slow when working with large data sets (e.g. a stack of daily grids say 144x73 elements 1970-to date). Does anyone have any tips for speedy retrieval? I'm thinking about typical drilling/slicing type operations.

Do look at the `R Data Import/Export' manual that ships with R (a recent version is needed), or the R FAQ or the list of packages on CRAN. You will find RNetCDF, ncdf and ncvar. -- Brian D.
