Rcpp - Linking to DLL from another package?
...u use Rcpp or not -- R only offers us C interfaces so C interfaces are all we got. And they don't know classes. I worked through that in some of my packages. See eg RcppXts which "extends" in your sense xts by allowing C++ level access from another package. The one key aspect is that _everything you want to call from B must be explicitly exported by A_. See Writing R Extensions for details. If you could rewrite your class A to be header-only then you could just include it via LinkingTo. But that is a different story. In short, "No Free Lunch" and no automagic mechanisms. Dirk...

Authentication delays in Samaba 3.0.10

This behavior seems to have changed from our samba 2.2 installation where the dialog would pop up ve...

Rcpp - Linking to DLL from another package?
Hi, I am trying to make a package B that extends another package A. Package A uses Rcpp, and I want to extend a class X used there. So package A has src/X.h and inst/include/X.h class X { ... } src/X.cpp X::X( arguments ) { ... } My package B wants to do this: DESCRIPTION [...] LinkingTo: Rcpp, RcppArmadillo, A Imports: Rcpp, RcppArmadillo, A src/Y.h class Y: public X { ... } src/Y.cpp

Netfilter, libpcap, ntop and promiscuous mode?
I have a really basic question (I think). We have two boxes connected to a lan segment on a hub. One is a Windows box running "Show Traffic", the other is a CentOS 5 Linux box running "ntop". Both boxes should be able to sniff all of the traffic on that hub (not a switch). The Windows box does just fine, Show Traffic is able to display traffic destined for other boxes
