I have tried to install INLA using this code:

install.packages("INLA",
                 repos = c(getOption("repos"),
                           INLA = ";), 
                 dep = TRUE)

I have also tried this code:

library("devtools")
devtools::install_github(repo = ";, ref = "stable", subdir = "rinla", build = FALSE)

My version of R Studio is: 2024.12.1

I get these warnings and errors:

Warning in install.packages : unable to access index for repository : cannot open URL '' Warning in install.packages : package ‘INLA’ is not available for this version of R

A version of this package for your version of R might be available elsewhere, see the ideas at .html#Installing-packages Warning in install.packages : unable to access index for repository .3: cannot open URL '.3/PACKAGES'

Thanks

Kind regards
