Dear R users!
I have a problem using tune() from e1071 package. I need to to tune a neural
network where response variable is a vector. I've used this function as it
shown below and I got the error:
tune.netWhole <- tune("nnet", x, y, ranges = list(...), tunecontrol = ...)
# weights: 28
initial value 10824.223491
iter 10 value 8687.908464
final value 8685.151182
Error in crossprod(pred - true.y) :
dims [product 58] do not match the length of object 
If someone has already handled with this problem, I'll be glad to read your
advices. Looking forward your answers.
