Return observed target values used for fitting ‘ann’ or ‘nnet’ ANN models.

1	observed(object)

object

an object of class ‘ann’ as returned by ann or of class ‘nnet’ as returned by nnet.

This function can be invoked by calling observed(x) for an object x of class ‘ann’ or ‘nnet’.

a 1-column matrix of observed target values.

# Get observed values of y used to train ann object `fit'.

data("ar9")
samp <- sample(1:1000, 200)
y <- ar9[samp, ncol(ar9)]
x <- ar9[samp, -ncol(ar9)]
x <- x[, c(1,4,9)]
fit <- ann(x, y, size = 1, act_hid = "tanh", act_out = "linear", rang = 0.1)
y_obs <- observed(fit)
