Hi dear List,
Another question related to the first one is about the compilation of that
code.
If the source of error is removed, the code compile correctly using
cxxfunction.
However, I get a warning message when I try to produce a package out of it
using
package.skeleton( "fun2", fun ):
In dump
I ran into the same kind of problem again, but this time I just can't find
what the correct syntax is:
I need to update a matrix stored in a list, by summing with an arma:: mat
object
the syntax MyList[j] += ArmaObject does not work.
On the other hand I can access the matrix object stored in those
I finally figured out, it was a syntax error, as the new assigned object was
not an arma:: mat but an element from a list
I took care of the problem by using ui = Rcpp::as(all_ui[i]) in
the reaffectation
Thank you again all for your help

Well ... that still make little sense. Variables are not protected; there is
nothing stopping you from re-assigning values, be it element-wise, row or
column-wise, or as a whole matrix. So I suspec
I've also written MCMC code using arma and have no trouble overwriting
(assuming that's what reaffectation is) matrices.

Well,
That's sound good,
The distribution I need are multivariate normal, inverse gaussian.
Though, the biggest issue is that for one of the parameter there is no
closed form so I am using Metropolis Hastings for it.
Any idea about this variable reaffectation thing?
It seems to be specific to arma
I'm not giving up yet. I'll implement the distribution that is
missing, and send you the example if you lay out your model w/
pseudocode.

Hi,
Thank you for your quick answer.
Sorry that I did not explain well enought my issue.
I did not know about cppbugs but I just checked and it does not seem that I
can use it for my model because it lacks some of the distribution I need.
The fraction of code could seems obscure but it is just the

You're not the only person working on MCMC w/ Rcpp.
I'm not sure about your exact question, but if you provide a .bug file
or write your model in pseudo code (i.e. alpha ~ dnorm(0, tau)), then
I'll write up a cppbugs example for you.

I started a few days ago coding with Rcpp to try to reduce the computing
time of a MCMC model.
However, I don't have experience with C/C++ and I can't figure out how to
reaffect a new content to a variable.
This seems probably very simpl
