Hi Sarah,
thank you very much for your answer. I have been spitting things out on
screen, but unfortunately I have not run it as a batch log, but in the
interactive window, so when the GUI crashed I was left without trace...
I guess I should google how to run it from a batch.
I should also explore using RData, I have ony been using csv files and
tables so far, it seems that can also bring some added performance.
As the main output of my process is a matrix, I would really need to
append to a matrix after each iteration. I have identified the
write.table append parameter-based solution, but that would only append
rows. Is there a way to slowly "grow" a matrix in both directions,
meaning append columns as well (it is a big distance matrix).
Thanks a lot for your help,
Cheers
Martin

Oh dear. No there isn't. I do a lot of very long runs, and have learned to write
out intermediate steps. Depending on what you are doing, saving the RData
file periodically may be appropriate, or writing out a csv file of
results so far,
or even just printing something to the output file (if you are using batch).
There may well be something more elegant, but these solutions have all worked
well for me in various situations.

Dear all,
I am using an R 2.10 installation on a Windows 203 server that I have no
control over. After a multi-day run I found that it was terminated/crashed.
Is there any log kept by R where I could see whether something/what
happened? The same process has been run beofre on a smaller dataset (also at
least a day of computing) without problems.
Thanks
Martin
