Hello Matt:

This is my situation, i can't install the package and i leave you the error code:

Downloading GitHub repo mattflor/chorddiag@master
These packages have more recent versions available.
It is recommended to update all of them.
Which would you like to update?

2: CRAN packages only
3: None
4: rlang (0.4.5 -> 0.4.6) [CRAN]

Sorry for that problem. As the error message suggests, the pander package is missing. After you have installed that one (e.g. by calling install.packages("pander"), you should then be able to install the chorddiag package.
