[Lemon-user] Integrating LGL with R via Rcpp

[Alpár Jüttner]

Hi Juan,

Thanks for sharing your experience. I am not familiar with R, but went
trough your blogpost and I found it really exciting.

At the end of your post (and at http://stackoverflow.com/) you have a
question about using LEMON without installing it. Is it a general issue
using Rcpp, or something LEMON specific?

In general, LEMON headers must be included like
#include<lemon/dijkstra.h>, indeed, but this shouldn't cause any problem
for you - simply create a lemon subdirectory within your include dir and
put the lemon headers there.

Regards,
Alpár

P.S. It was nice to find other happy users following the links in your
post.
