Rstudio crashed when I try to train a nnet model.

Hi,
I tried to run the code in another computer in RGui. This time program run until final iteration. But after the last iteration RGui quit without any error code. I mailed this issue to?Brian Ripley who is the maintainer of R nnet package. What can I do to solve this problem?

Hi Baki,
This should be a different issue. It looks like there is no problem in the R?terminal. Does?the crash happen every time when you run the code in RStudio? If so, this should be a bug in RStudio and you need to consult RStudio's mailing?list as R and RStudio are maintained by different teams.

Hi?Jiefei
I run the code below in RGui

nn2 <- nnet(TQ~.,data = train, size=c(15,15), linout=T, MaxNWts =4000, maxit=2000)

But I got the following output:
# weights:? 435initial? value 55650.887782?final? value 55650.887782?converged
Program early converged. Program didn't any calculations.?

Hi Baki,
Perhaps out of memory? Would you be able to run your code through the R terminal? It probably can give us more information to debug the issue.?

Hi,
I tried to train a neural network with following code:
nn2 <- nnet(TQ~.,data = train, size=c(15,15), linout=T, MaxNWts =4000, maxit=2000)

When I executed the code R studio crashed with following error:
"R Session Aborted
R encountered a fatal error.
The session was terminated.
Start new session"
When I set the hidden layer as c(15) as below the code works fine.
nn2 <- nnet(TQ~.,data = train, size=c(15), linout=T, MaxNWts =4000, maxit=2000)

What could be the problem?

Best regards.
