C++: Appending Values onto an R-Vector.
Hi folks. I posted this question a few days ago, but maybe it got lost
because of the code I included with it. I'm having a problem using the
SET_LENGTH() macro in an R extension I'm writing in C++. In a function
within the extension I use SET_LENGTH() to resize R vectors so as to
allow the concatenation of single values onto the vectors -- it's a
"push back" function to
