[R] Installing Rstreams lib

[Martina Pavlicova]

I thank prof Ripley for prompt answer. I did delete the problem parts of
the code in the C source file, which worked, but it slightly altered the
library. I did not know that there is a possibility to use a binary
connections in base R.

Thanks for the help.
