[R] Error handling

[Carsten Steinhoff]

Hi,

I have written an R-Procedure that automatically does a ML-Fit for some
datasets to a few
selected distributions. After any optimization the function writes the
estimated parameters into a variable.
My problem is now that sometimes the optimization failes and my program
stops with an error message.

What I want after a failed optimization is that there is written an error
msg
in the variable instead of stopping the program.

For the ML-Fit I use the "fitdistr" algorithm.

How could I do that ?

Thank you very very much!

Carsten
