[R] *** caught segfault *** :: a common problem in 3.0.2

[Frede Aakmann Tøgersen]

I think you are trying to access memory that you are not allowed to.

Or did you specify the type of all of your data to be of the right ones?

The segfault message at least say so.

Why don't you have as.integer for ncol(Y), nrow(Y)??

So are you having ncol(Y), nrow(Y) in the right order when you use t(Y)??

Why don't you have as.double for t(Y)??

Is this correct: as.integer(as.numeric(l) -     1)??

Should as.numeric be as.double?

Have you checked that all indexes for your arrays in the C/C++ code are defined correctly with the arguments of your  .Call()??


Yours sincerely / Med venlig hilsen
