Error installing flipRegression package from GitHub

Hello! I'm fairly new to R and I'm trying to install the flipRegression GitHub package.

require(devtools)
install_github("Displayr/flipRegression", dependencies = NA)

At first it gives me the following error:

Error: Failed to install 'unknown package' from GitHub:
  HTTP error 403.
  API rate limit exceeded for 99.229.10.87. (But here's the good news: Authenticated requests get a higher rate limit. Check out the documentation for more details.)

  Rate limit remaining: 0/60
  Rate limit reset at: 2021-03-30 23:03:25 UTC

  To increase your GitHub API rate limit
  - Use `usethis::browse_github_pat()` to create a Personal Access Token.
  - Use `usethis::edit_r_environ()` and add the token as `GITHUB_PAT`.

I created a PAT and ran the following:

library(credentials)
set_github_pat()

Now, when I try to install the package again, I get prompts to update packages and the following error:

> install_github("Displayr/flipRegression", dependencies = NA)
Using github PAT from envvar GITHUB_PAT

These packages have more recent versions available.
It is recommended to update all of them.
Which would you like to update?
