lxh,
A quick word r.e. list etiquette -- you can help others process your
request by including in your email a short & informative title, and a
one or two sentence description of what you're trying to accomplish.
I'm not on windows, so all I can say is that it works for me. Have you
verified that RcppArmadillo installed without error?
The other thing you can try is use the following to observe the
details of the compilation process:
sourceCpp('armaPRI.cpp', verbose=TRUE)
hth,
Christian
