radon1 test failure

[jhjourdan]

On my machine, the radon1 test fails :

/usr/bin/time -o ./benchmark.output --append --format="%e %U %S" ./radon1

error: max(): object has no elements

terminate called after throwing an instance of 'std::logic_error'
what():
make: *** [benchmark] Erreur 6

Thanks !

hmm, what OS and what version of armadillo do you have installed, and
what gcc are you using?

I am using Fedora 16, with the last version of armadillo (3.2.3), and
gcc 4.6.3.

Here is a stack trace obtained by disabling optimisations and enabling -g :

Just guessing but it looks like that kind of error could happen if an empty matrix is created for the radon dataset.

Did you down load the data and modify the file location in the source code?

string file("/home/warmstrong/dvl/scripts/mcmc/radon/srrs.csv");

Ok, sorry, I should have looked into the radon1.cpp file !

I was assuming test cases were self-contained. BTW, would it be possible
to include these data in the git repo ?

no worries.

most of the test cases are self-contained. However, the radon dataset
is pretty large.

In my rcppbugs example, I read the file directly off of the website,
but it's a little harder to do that in c++.
