I am new to R (so your patience and support is appreciated)! I looked up this issue, but still could not find a solution that worked. I am trying to install the "party" package in R. However, I keep receiving the following error messages:
> **ld: warning: directory not found for option**
> '-L/usr/local/lib/gcc/x86_64-apple-darwin13.0.0/4.8.2' ld: **library not

I successfully installed "mvtnorm" and "multcomp" as suggested on a similar thread here: [Error installing PARTY package in R
However, I still could not install PARTY, so I checked this thread: error install packages("party") - R studio IDE
The above thread led me to https://www.r-bloggers.com/installing-r-on-os-x/
However, I am wondering if there is a more simple solution that does not require me downloading additional software that will force me to update my version of Mac OS X to 10.13.6 or later. I currently have OS X Yosemite (version 10.10.5) and am nervous about updating, since I have heard mixed reviews.
Could someone please advise? I am trying to install "party" for a course assignment, and the "non-zero exit status" and "ld" warnings should not be what I am wasting time on! :-(
Thank you so much!
