Hi, dear R help
I am trying to use optim inside a for loop:
##For example. a: intial guess. b: result. f: function to be minimized
for (i in 1:10) {
b[i] <- optim(a[i], f)}
However, some intial values cause error in optim function (e.g. " system is
computationally singular..."). Then the for loop stops and won't try the
following initial guesses.
What can I do if I want the for loop procedure to finish all the initial
guesses? I know this may be a stupid question.. but I am not familar with R
optim. So thankyou very much for any help..
Sirius
