Thank you very much for the reply.
And now I have to a apologize for my late response.
I was quite a while out of the office.
This is exactly what I was looking for. I think it will be of great help
to have this implemented in a package.

I apologize for not replying earlier. I think that you can combine the
polylist class from the maptools package with the csr function in the
splancs package to position points randomly (the gridpts() finction can
be used instead of csr() to give grid points):
Could you indicate whether this function is any use, and if you would
it added to some suitable package?
