I get an error : unable to install package ' digest '

Have you tried to install digest manually? do you get any error message? This is the command to install the package.

install.packages("digest")

Yes, getting same error

> install.packages('digest')

  There is a binary version available but the
  source version is later:
       binary source needs_compilation
digest 0.6.21 0.6.22              TRUE

Do you want to install from sources the package which needs compilation? (Yes/no/cancel) YES
installing the source package ‘digest’

Some times is hard to compile packages from source on macOS if you don't need the latest version, try installing the binary version by answering "No" when asked if you want to install from source.

If for some reason you need to install the latest version from source, then the first thing to try is to update Xcode in your system

xcode-select --install

Here are some installation instructions
