remotes::install_github("tylermorganwall/rayshader", version = "0.31.0")

and

install_version("rayshader", version = "0.31.0", repos = "https://api.github.com/users/tylermorganwall/repos")

    If you had an earlier version I would have called `remove.packages` first. But I should ask "WHY" do you think you did something wrong. Did you (1) get an error message or (2) a warning message or (3) did the downgrade just not succeed? On SO is it important to include the full text of any warnings or error messages. – IRTFM Mar 10 '23 at 05:01
  • The result of the installation is the latest version. – Eriza Mar 10 '23 at 05:25
  • Do you see documentation that says `version` is a parameter for that function? – IRTFM Mar 10 '23 at 07:27
  • in `install_version()` use parameter `version`. i don't know in `install_github()` – Eriza Mar 10 '23 at 07:31
  • It was not I looked at the current documentation for `install_github` and the function that is documented as being called to handle the "dots" optional arguments. I was attempting to get the OP to learn to read the help pages and understand that they could not expect a warning for a non-existent argument. – IRTFM Mar 10 '23 at 15:28
