This is both a specific question and a general one. First, I am running
'fitdistr' from library(MASS) and I get the following:
Error in fitdistr(templist, "weibull") : optimization failed
What is the cause of the error? How can I tell? Can I just catch this
error, report it and move to the next set of data (eat the exception)?
You can use try() or tryCatch() to both allow further calculation and to
save the current input to fitdistr() for further study.
Alternatively, you can set options(error=recover) - see ?recover -
and see where the error comes from.

Thank you.
