[R] Rstudio crashed when I try to train a nnet model.

[Jiefei Wang]

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.

Best,
Jiefei
