Hello,

I have been having difficulties opening netcdf files using the netcdf
library.  I am able to successfully open the file and I can determine the
names and size.  However, when I try to read it I receive an error.
Reading the documentation, I am wondering if this might be due to a
difference between netcdf version 2 and more recent netcdf format? I've
tried using different values for the count option without luck.  I have
had success reading this file into matlab.


> library(netCDF)
> aaa<-
open.netCDF("/scratch/pocernic/int_fcst.20021201.0010.nc")
> class(aaa)
[1] "netCDF"
> summary(aaa)
netCDF file /scratch/pocernic/int_fcst.20021201.0010.nc is open
$types
 [1] "integer" "numeric" "numeric"
"integer" "integer" "integer" "single"
 [8] "single"  "single"  "single"
"single"  "single"  "single"  "single"
[15] "single"  "single"  "single"
"single"  "single"  "single"  "single"
[22] "single"  "single"  "single"
"single"
 ... etc

## when I try to read it, I get the following error.

> bbb<- read.netCDF(aaa)
Error: dim: Invalid dimension vector

Thanks

Matt
