But you have R installed in a path with spaces. That sometimes creates
problems, and is still recommended against in question 2.2 of the 'R on
Windows FAQ' at
https://cran.r-project.org/bin/windows/base/rw-FAQ.html#How-do-I-install-R-for-Windows_003f

Worse your include path seems to be on a network drive:
-I"//INFPWFS1014.ad.unsw.edu.au/Staff081z3271570/R/...."

As this fails for you, I would suggest a local 'on the machine'
installation.

I always put mine into c:/opt/R/R-current/ instead of c:/R/R-3.3.1, say.

You don't need to do that. As you can see R knew where Rcpp was.

And I don't see screenshots as I read email in text mode. Sorry.
