I have good news and bad news.
I found the source of the error. In your wrapper function
logsumexp <- function(x, a = NULL)
{
x <- as.matrix(x)
a <- if(is.null(a)) rep(double(0), ncol(x)) else as.vector(a)
logsumexp_Rcpp(x,a)
}
the expression rep(double(0), ncol(x)) is not doing what you t
I think it is worth asking Martin Maechler if he could expose more
SuiteSparse functionality through the Matrix package.

This could well be due to incompatible thread models (win32 vs posix).

You just need to put a new template specialization of "wrap" for the
subview_col class in RcppArmadilloWrap.h based on the existing one for the
subview class. And throw in one for subview_row for good measure.

This is related to David Shih's thread about modifying input arguments
but I think it needs its own thread.
I found a problem when I tried porting some Rcpp code to run outside of
Rcpp by providing my own NumericVector implementation based on STL
vectors. In Rcpp it is possible to obtain a non-con

Thanks John. I learned something new today. It is probably worth mentioning
this in the manual.

And another 2 cents from me.
A package is the basic unit of functionality in R. Whatever
functionality you are providing, I think a package is the best way to
deliver it. There is a well developed framework for versioning,
dependency resolution, testing, and distribution.
If you choose some other
