ERROR: compilation failed for package ‘png’
* removing ‘/Library/Frameworks/R.framework/Versions/4.2/Resources/library/png’
Warning in install.packages :
installation of package ‘png’ had non-zero exit status
The downloaded source packages are in
‘/private/var/folders/3m/h7n5_xtd1kz3xm1pww2bkh640000gn/T/RtmpxDvxeF/downloaded_packages’
Try again, and this time when you are offered the opportunity to install a more recent version from source, just say no.
non-zero exit status that the attempt to compile the source code failed, as it often does in macOS because of its non-standard compiler toolchain. So, if it doesn't work the first time, it's not going to work without more time trouble and effort that most people using R are able or willing to put in.
