RNetCDF: retrieving variable names and units
There are a number of functions in the package to inquire about the
file contents. See library(help = RNetCDF).
For example:
library(RNetCDF)
nc <- open.nc("file.nc")
var.inq.nc(nc, 0)
$id
[1] 0
$name
[1] "longitude_U"
$type
[1] "NC_DOUBLE"
$ndims
[1] 1
$dimids
[1] 1
$natts
[1] 0
You can then read from the file with something like this:
obj0 <- var.inq.nc(nc, 0)
dat <- var.get.nc(nc, obj0$name, start = ...)
Going with ncdf or ncdf4 package is probably better ( I just happen to
be more familiar with RNetCDF.)
Cheers, Mike.

Dear List, does anybody has experience with the RNetCDF package? I manage to open a connection and copy data from a ncdf file but would need a way to automatically retrieve variable names (ideally all of them from one file) and units from the file. Any ideas? Jannis
