Is there any way to test if R is running on a Mac? I usually use

Thanks, Gregor
What is in .Platform$path.sep?
Windows has ;, unix has :.

I am writing a package.
Please, study the sequence of my actions below, and comment, what's
incorrect.
The package contains pure R code.

This produces the file ac9_0.1.zip (The package
I am writing a package, which contains several functions and variables.
The variables are for internal use by functions.
Functions are ment to be callable by a user.
However, the function cannot access these variables.
The package contains only R code, and was created using package.skeleton

I am sorry, my previous questions about hiding variables from users in a
package were obscure and vague, and would like to clarify them.
This should be a basic question.
I am writing my first package.
It has several functions, which should be callable by users.
These functions use several

We can only guess at this, not having function AB2C.

The function AB2C now sees ac9nw, and gives similar errors, related to other
hidden variables.

That was not the case.

Since that, indices in the array were calculated incorrectly, and the

I am writing bindings to the neural network simulator SNNS.
At present I have used only .C interface, now I'm studying .Call interface.
I have adapted the example from page 77 of r-exts.pdf, however, it crashes

I use MingW as recommended by Duncan Murdoch.
Please, tell me what I am missing.
I am writing bindings to the C library (neural network simulator SNNS).
DLL was produced with the command
R CMD SHLIB [source with C-wrappers, callable from R with .C and all
sources from the snns kernel]
I used latest MinGW.
The problem is. R crashes with the segmentation violation.
