回答1:
You installed R in a path with spaces. Which breaks things.
R defaults to this even though the R-on-Windows FAQ says not to do this.
The next Rcpp version has a defense against this. Until then, move your R installation.
Oh, and I answered this very question probably three times already on SO alone...
