Indeed -- big thanks to the Rcpp devs. Rcpp is definitely an indispensable tool in the tool-belt.

A big thanks from me too, to the Rcpp team for a great piece of software.

Hi, Dirk. I guess it takes a village to raise a successful R package, so in that sense your "Thank You!" to the users of Rcpp & Friends is appropriate. But I like to think that for both kids and R packages the "parents" play an essential role. I've been waiting for somebody to offer the obvious "back at you, dude!" response, but I haven't seen one.

[Rcpp-devel] Rcpp plugin use adding -I for current directory
Someone recently asked (and I can't find it here so it may have been on
StackOverflow) how to tell inline to also consider the current working
directory for includes.
I answered that one can't as inline / cxxfunction always switches to a
temporary directory created by R. Turns out that one can in fact, as it is
the known current working directory. Romain had added this in one of our
examples:
settings <- getPlugin("Rcpp")
settings$env$PKG_CXXFLAGS <- paste("-I", getwd(), sep="")
and then uses settings=settings in the call to cxxfunction.
Nice trick.
Regards, Dirk
