As I was going through the Rcpp Quick Reference Guide, I just found a
solution to my problem :
In the .R file of my package, in the .Call function, there was no
argument telling my function needed an input variable... I added this,
rebuilt/installed the package, and now it works.
The new .R file :
Hi all,
R_tryEval function will tell whether the expression executed properly or
not, but it is not giving what is the error by executing the expression.
How can we know the error message if execution fails, can anyone help me out
in this.
Thanks in advance.

Dear all,
I got some problems with the variadic argument "..." in Rcpp.
Suppose i have a R function f:
f <- function(x,...)
{
blabla
}
In another R function, i want to pass this f as an argument to a C++
function, along with all its own parameters, i.e. x and the "...".
I found a method tha
Hi everyone,
I have an issue when creating a package using Rcpp, on a Windows7,
32bits computer. I haven’t found anything on the net or help pdfs that
looks like my error, so maybe you can help me.
I have used the Rcpp.package.skeleton function with the
example_code=TRUE argument, in order to see

I'm getting the picture now. Thanks for the additional example. And
Doug, sorry I still missed your earlier point.

Thank you all for the responses.
Christian, I didn't know about the copy_aux_mem option. I will have to
take a look at that.
Dirk, thanks for looking into the 64-bit matrix indices.
Doug, the place in my code where I get the error is when I multiply
matrices. I might have matrices X and Y, whe

Venelin,
You actually managed to ask several unrelated questions in a single post. It
may be easier if you ask the separately.
As for your question on IDEs: nobody has a fully reliable parser for C++
embedded in an IDE so I would not recommend taking the highlighting too
seriously. And yes,

Hello,
Many thanks to Dirk for the quick and helpful answer. Rcpp is a great
project, really! Yet, I've been struggling a bit, trying to find what what
functionality is there.
