The error message is indicating that the package could not be found on GitHub with the provided repository owner and repository name.
Here are a few possible explanations for the error:
- The repository name is incorrect, please double check if you typed the correct repository name.
- You may not have the required permissions to access the repository. This could be because the repository is private and you haven't been granted access, or because the repository has been deleted.
- The repository may not exist anymore or it may have been archived.
One thing you can check is if the package is on CRAN, if so you can use
install.packages("package_name") to install it, if not you may have to contact the repository owner to check what's going on.
If you are sure that the repository name is correct and you have the required permissions to access it, then the issue may be with the package. You could try to install the package from a local copy of the package by specifying the path to the package.
Another thing you can do is to check the repository on Github to see if it's still there, if the repository is gone then you can't install the package from Github.
Additionally, you could try to troubleshoot the problem by checking the package's
DESCRIPTION file and
NAMESPACE file, and make sure that the package is properly formatted and all dependencies are listed.
