[R] about netcdf files

[Jon Skoien]

You could try with the brick function from the raster package.

bvar = brick(netcdfName)

This uses the ncdf4 functions for opening and reading the netcdf, but 
makes it easier to extract data for each day:

p1 = rasterToPoints(bvar[[1]])
and write p1 to csv.

Best,
Jon
