Ahmadou,
Thanks so much for the follow-up! As I don't use OS X, I am mostly a
bystander on these usage questions.

|
| cppFunction(code =
| 'arma::mat armatrans(arma::mat A) {
| return arma::trans(A);

|
| armatrans(matrix(1:6, ncol = 3))
| ## [,1] [,2]
| ## [1,] 1 2
| ## [2,] 3 4
| ## [3,] 5 6
|
|

| Mavericks
All excellent points and straigth to the core of the issue. There is no
fundamental problem but one needs to get one's ducks into a neat row. [1]

And even then it seems confusing. I had an (unrelated, different package,
simply using Rcpp too) report on RQuantLib not loading and pointed to Brian
Ripley's recent post
http://article.gmane.org/gmane.comp.lang.r.mac/8675
which also indicated that some 3rd party libraries need a rebuild for
Mavericks before binary packages can work:
Some of the Mavericks binary packages are missing for good reason. The
C++ binary interface for the Xcode 5.x compilers in Mavericks is
completely different, so external software has to be compiled with those
compilers. This affects CRAN packages
RQuantlib RProtoBuf RVowalWabbit rgdal rjags rzmq
I maintain the first three, if someone wants to help ... maybe contact me
off-list? [ And the third ships its own library code, so Brian Ripley would
appear to be wrong here. ]
| Hope it helps
Sure did. Thanks again.
Dirk
[1] Which to me as a non-user of OS X still seems harder than on other OS's
but whenever I say that I get yelled at by the most vocal OS X fanboys so I
try not to mention it too often :)
