I am really struggling to get R commander to run,
I managed to get data.table to install using:
install.packages("data.table", type = "binary")
But i am now getting the error message:
library(Rcmdr)
xcode-select: note: no developer tools were found at '/Applications/Xcode.app', requesting install. Choose an option in the dialog to download the command line developer tools.
Error: package or namespace load failed for ‘Rcmdr’:
.onLoad failed in loadNamespace() for 'tcltk', details:
call: dyn.load(file, DLLpath = DLLpath, ...)
error: unable to load shared object '/Library/Frameworks/R.framework/Versions/4.0/Resources/library/tcltk/libs/tcltk.so':

Reason: image not found
In addition: Warning message:

Judging from your error messages, there are a couple of dependencies that Rcmdr needs that are missing in MacOS.
The first is the command line components for xcode in order to compile some packages in R, as well as additional functionality such as git. You don't need to install all of Xcode, but in the terminal, type xcode-select --install
This addresses the error message: xcode-select: note: no developer tools were found at '/Applications/Xcode.app', requesting install. Choose an option in the dialog to download the command line developer tools.
The second missing component is Xquartz, which is a X11 windowing system. This can be installed from the link on https://www.xquartz.org/ or via homebrew as brew cask install xquartz.
This addresses the error message: Library not loaded: /opt/X11/lib/libX11.6.dylib and is a dependency of tcktk.
Unfortunately that is coming back saying "Can't install the software because it is not currently available from the Software Update server". I assume that's not something I can work around?
Hmm. Sounds like something is blocking the network connection. There's also a link for various versions of Command Line Tools for Xcode (e.g. 11.5 and 12) at https://developer.apple.com/download/more/. You may have to sign in using an AppleID account, and the basic level is free if you agree to the User Agreement.
