R package doesn't install from github

Question

I am using RStudio with R (Version 4.0.2) and I am trying to install this climate package from github: https://github.com/SantanderMetGroup/climate4R when I type: install_github("SantanderMetGroup/climate4R")

I get this error:
Error: Failed to install 'unknown package' from GitHub:
  HTTP error 404.
  Not Found

  Did you spell the repo owner (`SantanderMetGroup`) and repo name (`climate4R`) correctly?
  - If spelling is correct, check that you have the required permissions to access the repo.

I also downloaded the zipped package and tried to manually install the package within rstudio and got this error:

Installing package into ‘C:/Users/...../Documents/R/win-library/4.0’
(as ‘lib’ is unspecified)
Warning in install.packages :
  cannot open compressed file 'climate4R-master/DESCRIPTION', probable reason 'No such file or directory'
Error in install.packages : cannot open the connection

Why is it not installing? I have downloaded packages from github before with no problems.

UPDATED HERE: I had already tried what is suggested below, but it also didn't work. I wanted to check first if I had missed something and it was possible to download the package all at once. When I input this:

library(devtools)
install_github(c("SantanderMetGroup/loadeR.java",
                   "SantanderMetGroup/climate4R.UDG",
                   "SantanderMetGroup/loadeR",
                   "SantanderMetGroup/transformeR",
                   "SantanderMetGroup/visualizeR",
                   "SantanderMetGroup/downscaleR"))

I get the following error:

Answer 1

As already pointed out, the GitHub Repo is not an R package by itself.

Here from their GitHub Readme how to install their collection of packages that form the climate4R toolset.

library(devtools)
install_github(c("SantanderMetGroup/loadeR.java",
             "SantanderMetGroup/climate4R.UDG",
             "SantanderMetGroup/loadeR",
             "SantanderMetGroup/transformeR",
             "SantanderMetGroup/visualizeR",
             "SantanderMetGroup/downscaleR"))

Answer 2

In order to install this package, I had to install this:JDK 13 https://www.oracle.com/java/technologies/javase-jdk13-downloads.html

This allowed each of the packages to be installed correctly.
