[R] Error in Rcpp/inline (Windows XP)

[Prof Brian Ripley]

Did you read the posting guide (it says R-help is not for questions 
about compiled code)?

Or the rw-FAQ (it warned you that lots of contributed packages did not 
take account of spaces in path names, so suggested you install R in a 
path without one)?

This is a bug in one of the packages you are using, so you could 
(following the posting guide) discuss it with the package maintainers. 
But it is so common that you would do well to take the defensive 
action recommended in the rw-FAQ.
