Subject: rbind/timestamp problem

Thank you,
now it works. I would never have never found the source of the problem.
I am trying
to build a data frame with results from a sensitivity analysis
for a model. I use rbind because the number of rows is
unkown and i use the timestamp as a hint for the students
that they do not analyse data from last week :-).
Anyway, thank you very much, it helped a lot.
Greetings,
Georg
