Hello, I've created a NetCDF convention to amass into one
outputfile results contained in many (e.g. 50) NetCDF files
(of the AnDI for spectrometry type). Data in the new
convention include two 3-D arrays, with their unlimited
dimension being the number of input files. But these
conventions/types may be unimportant to my question.
After some coding false starts, I can now iterative through
a list of input files and load data into the output file
without obvious memory problems. But all stops at iteration
38, when the output file just exceeds 2 gigabytes,
specifically, when it is 2,097,144 kilobytes.
My question: Have I run up against a NetCDF file size
Limitation? Or is this some glitch in R or in Windows?
Thanks,
-John
P.S. I'm working in the R (v. 2.3.1) statistical programming
environment. I use Pavel Michna's RNetCDF (v.1.2-1) package
within R to access netcdf (v. 3) library functions. This is
all happening on a Windows XP laptop with 512 M RAM. The command
in my iteration that fails is "var.put.nc". The error is
generated from a line "stop(nc$errmsg, call. = FALSE). The error
message is "Invalid Argument". -JT
