Dear all, this is my first time, and just begin to use R. But I've a question about optimization using optimx library. It could sound stupid by I'm a bit affraid with the problem, because anything I try, anything Error. The procedure was: optimx(par="10,71,1",fn=(Prey*Provisioning)/Risk, control=list("maximize))
well the problem lies in the initial value parameters, again and again, R tells me that it is not possible to optimize the function at this values, even though these are real estimations. Any suggestion?
