Thanks for passing this along. Rcpp has come a long way. It could be very useful as we add more type conversions. The inline compilation is also cool for experimentation.<br><br>Michael<br><br><div class="gmail_quote">On Tue, Jan 19, 2010 at 1:50 AM, Romain Francois <span dir="ltr"><<a href="mailto:romain.francois@dbmail.com">romain.francois@dbmail.com</a>></span> wrote:<br>

<br>
I just wanted to draw your attention to the new version of Rcpp, that I<br>
think might be useful for qtinterfaces (maybe not).<br>
<br>
Rcpp has been completely redesigned over the holidays (while keeping the<br>
existing interface). Now we have many C++ classes that basically act as<br>
proxy classes for the SEXP they encapsulate. So that the object takes<br>
care of protection/release to the garbage collection.<br>
<br>
We cover just about every (useful) SEXP type. For example, manipulating<br>
a character vector can look like this :<br>
<br>
/* creating a character vector of two elements */<br>
Rcpp::CharacterVector x(2);<br>
x[0] = "foo" ;<br>
x[1] = "bar" ;<br>
