Typical code would look something like this:
library('ncdf'')
filename <- 'data.nc'
varname <- 'Temperature'
ncid <- open.ncdf( filename )
data <- get.var.ncdf( ncid, varname )
If you need to see what variables the file contains to get the
variable names, just do a "print(ncid)" after you open it.
If it is a very large file, too large for the data to fit in memory
all at once, you can step through and read each timestep in the file
separately using the "start=" and "count=" arguments to the
get.var.ncdf() call.
