[R] whether R can import netcdf file format data ?

[Benjamin Lloyd-Hughes]

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.

Cheers, Ben

It can read from and write to them, at least.

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.
