predicting class for new data using neuralnet

Question

I\'m trying to predict the class (0 or 1) for a test dataset using a neural network trained using the neuralnet package in R.

The data I have looks as follows:

Answer 1

I had the same problem. I put debugonce(neuralnet) and I discovered neuralnet was multiplying matrix from different sizes.

I solved the problem removing the y column from test with this function

columns <- c("x1","x2","x3","x4")
covariate <- subset(test, select = columns)
