Dear Nikos,

Can you give us a bit more context?  What is it you want to achieve?
How are you using r.stats and what is it you want to do with the
output?

Personally, I am not too familiar with performance implications of
NumPy vs. plain Python, but rather use NumPy for convenience in
matrix/table operations (avoiding pandas)...

```
for category in categories:
   statistics_filename = prefix + '_' + category
   r.stats(input=(base,reclassified),
           output=statistics_filename,
           flags='ncapl',
           separator=',',
           quiet=True)
```

Instead, I want to (modify the above so as to) collect/direct all
iterations in one output file.

The question, finally, seems to be: use Python's 'csv' library or prefer
NumPy? The number of records might reach tens of thousands (or more).

Nikos
