LinkingTo: Rcpp

I think you need the line:
LinkingTo: Rcpp
in the DESCRIPTION file to avoid this error:
g++ -I/home/R/R-3.2.4/lib64/R/include -DNDEBUG -I/usr/local/include -fpic -g -O2 -c mean_c.cpp -o mean_c.o
mean_c.cpp:1:18: fatal error: Rcpp.h: No such file or directory
#include <Rcpp.h>
when building the package

Thanks. I didn't spot the error.

The book isn't really a package. The DESCRIPTION file is just used to list dependencies.
