Thank you. I will have a go at changing the directory when I upgrade to R-2.15.2 .

If you install into a library without spaces in the path everything should work correctly (see: http://stackoverflow.com/questions/9764495/how-to-get-rcpp-to-work-in-r- on-a-windows-xp-platform) J.J.

However, I am unable to get your Finding Pi example (http://dirk.eddelbuettel.com/blog/2012/11/20/#rcpp_attributes_pi_exampl e ) to work. I have the C++ file and the R script, but sourceCpp fails. When I set showOutput and verbose to be TRUE then I get the following message. Looking through the message, it appears that the g++ command line does not have one of the parameters in quotes (highlighted in green) which is why it might be interpreted as two (missing) parameters. It is beyond my limited knowledge whether this is a bug or a problem with the configuration of my system, details of which are attached. If you have any suggestions on how to fix this, so that I can go on and use Rcpp, then I would be grateful.
