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 converged Error in crossprod(pred - true.y) : dims [product 58] do not match the length of object [1218] If someone has already handled with this problem, I'll be glad to read your advices. Looking forward your answers. -- View this message in context: http://r.789695.n4.nabble.com/Using-matrix-as-a-response-variable-tp3687296p3687296.html Sent from the R help mailing list archive at Nabble.com.
