Dear, R experts.
Does anybody have experience with 'optim' function?
I have an error message as the following.
Error in optim(transcoefs, fn = hfdeviance, gr = hfdeviance.grad, method
= "BFGS", :
initial value in vmmin is not finite
I want to make a comment when this happen.
Is there way I can put *my* message after this error occur?
Thanks in advance
