Hi, I was about to send the email below, but eventually I got it to work. I'm sharing it anyway since others might run into similar issues.
Basically, I needed the latest macOS command line tools installed, but getting them installed was tricky. I installed Xcode 10.1 (10B61) from the Mac App Store, then installed a version of the command line tools via https://download.developer.apple.com/Developer_Tools/Command_Line_Tools_macOS_10.14_for_Xcode_10.1_Beta_2/Command_Line_Tools_macOS_10.14_for_Xcode_10.1_Beta_2.dmg, rebooted, then under "settings", "software update" detected that there was a newer version. Finally, I was then able to install the backports R package. Best, Leo ## Successful install: > install.packages('backports') Warning: unable to access index for repository https://cloud.r-project.org/bin/macosx/el-capitan/contrib/3.6: cannot open URL 'https://cloud.r-project.org/bin/macosx/el-capitan/contrib/3.6/PACKAGES' Package which is only available in source form, and may need compilation of C/C++/Fortran: ‘backports’ Do you want to attempt to install these from sources?

For that I tried installing R 3.6 with all my current R 3.5 packages. I quickly ran into problems trying to install devtools. Basically, the backports package is not available as a binary and the compilation from source fails because it can't find an stdlib.h file. I also recently updated my Mac with the new OS as well as the latest Xcode (which in theory now comes with the command line tools that should include that stdlib.h file). I also installed the latest command line tools but still ran into the same issue. Has anyone else seen this issue and resolved it? If so, what step and I missing?
