I want to perform neural network analysis for a survival data (the lung dataset in the survival package). However, i got the following Error. Error in x - y : non-conformable arrays The following is the source code. nn.model <- neuralnet(Surv(time, status) ~ ., data = train.data, hidden = c(3, 2), linear.output = FALSE) Many thanks.

The package does not support survival data. There is no loss function appropriate to survival data implemented.

We could check that and give a meaningful error message though.
