Hi all --

I am working on 64-bit Windows XP.  I'm not a very technical person when it
comes to the command line stuff, so please forgive me if this is a stupid
question.

I have a bunch of HDF files, and I want to dump a single PM25 data layer
from each file to .txt by invoking ncdump.exe from system().  Here's a
sample command string:

"C:/ncdump -v PM25 C:/01aug2010.hdf > C:/01aug2010.txt"

This works perfectly in Python, but does not actually generate the .txt
file in R when:

system(command)

It does show the output on the console, if flagged to do so, and I can
capture the output to an R object with intern = T.  I assume there is some
problem with the way I have specified how to get the output to the text
file (i.e. the ">"), but experimentation with other options has not gone
well.

Can anyone advise?

Thanks!

Sarah
