[Rd] R, Macports and C++ streams

[Kjell Konis]

I found this in Writing R Extensions:

"Using C++ iostreams, as in this example, is best avoided. There is no  
guarantee that the output will appear in the R console, and indeed it  
will not on the R for Windows console. Use R code or the C entry  
points (see Printing) for all I/O if at all possible."

That is, use Rprintf() instead. The fact that your code works with one  
version of gcc and not another can probably be chalked up to  
coincidence.
