Hello. I am having a huge amount of difficulty getting rstan to install and run on a fresh R installation. I have been speaking with one of the devs here (Rstan installation troubles - #23 by Ruben222 - RStan - The Stan Forums) and it sounds like there is an issue with my rtools.
In short, it doesn't seem like I am able to install packages from source for some reason. IE running this code:
Gives this output:
Warning in install.packages : installation of package ‘Rcpp’ had non-zero exit status
Any help would be greatly appreciated as I am completely stuck.
