I apologize in advance if I could've formatted this better - I am new to Stack Overflow. I am trying to install the kableExtra package. While I'm able to install it, I keep getting this error message when trying to load the package. How exactly can I fix this?
install.packages("kableExtra", dependencies = TRUE)
library(kableExtra)
Error: package or namespace load failed for ‘kableExtra’ in dyn.load(file, DLLpath = DLLpath, ...):

You appear to have a broken copy of the systemfonts package. You could try reinstalling it before installing kableExtra, but it might fail to install, because you also appear to be missing the /opt/X11/lib/libfreetype.6.dylib dynamic library. You may need to install that: but I can't suggest how to do that without knowing more about your system.
You edited your question to include the result of running sessionInfo(); thanks! What that tells me is that you're running on a Mac: so you would install XQuartz to get the X11 libs. I think that should get you libfreetype.
I also see that you are running R version 3.6.1. That's 2 years old, and current packages may not be available for it. It's generally a good idea to stay current, and R 4.1.0 was recently released, so I'd suggest updating to that version. Before you update, run pkgnames <- rownames(installed.packages(priority = "NA")); dput(pkgnames) and save the results to a file. Then update R, and run
pkgnames <- [ the long string you saved ]
install.packages(pkgnames)
to install the latest versions of any contributed packages you were using.
