Hi all!
I'm running some simulations and I need to estimate some paramaters with
optim( ),
in some cases optim stops with the next message:
"L-BFGS-B needs finite values of 'fn' "
I would like to know how to include and "if" condition when this happen,
could it be something like:
myfun <- optim(....) # run my function
????
if(myfun == ERROR) ..... # when the error message is "L-BFGS-B needs
finite values of 'fn'
????
I've succesfully achieved when, for example convergence is not reached,
if(myfun$convergence != 0)
but I don't know how to do it in the other case
Any help??
Thanks in advance,
Dae-Jin
