I recently updated to R 3.6.3 for Mac OX (I currently have 10.14). My XQuartz is updated, and I have clang 7.0.0 and gfortran-6.1 installed.
However, when I tried installing the 'ppcor' package I would get this error message
I tried changing my cran mirror and regardless of the mirror I chose I would get this error message:
Warning: failed to download mirrors file (cannot open URL 'https://cran.r-project.org/CRAN_mirrors.csv'); using local file '/Library/Frameworks/R.framework/Resources/doc/CRAN_mirrors.csv'
In download.file(url, destfile = f, quiet = TRUE) :
URL 'https://cran.r-project.org/CRAN_mirrors.csv': status was 'SSL connect error'
I am new to R and any help would be much appreciated
