Installing INLA package

Dear all

I am using RStudio version 4.5.0 and I am trying to install INLA package and I keep on getting an error.

I used this R-studio:

install.packages("INLA",repos=c(getOption("repos"),INLA="Index of /R/stable"), dep=TRUE)
install.packages("INLA",repos=c(getOption("repos"),INLA="Index of /R/testing"), dep=TRUE)

inla.upgrade() # for the stable version
inla.upgrade(testing=TRUE) # for the testing version

if (!requireNamespace("BiocManager", quietly = TRUE))
install.packages("BiocManager")
BiocManager::install(c("graph", "Rgraphviz"), dep=TRUE)

inla.binary.install()

library("devtools")
devtools::install_github(repo = "GitHub - hrue/r-inla: This is the public repository for the r-inla project", ref = "stable", subdir = "rinla", build = FALSE)

install.packages("INLA",
repos = c(getOption("repos"),
INLA = "Index of /R/stable"),
type = "source",
dep = TRUE)

Thank you advanced

You should be able to use:

install.packages("INLA",repos=c(getOption("repos"),INLA="https://inla.r-inla-download.org/R/stable"), dep=TRUE)

What error message did you get / do you get running that?

This is what I get:
install.packages("INLA",repos=c(getOption("repos"),INLA="Index of /R/stable"), dep=TRUE)
WARNING: Rtools is required to build R packages but is not currently installed. Please download and install the appropriate version of Rtools before proceeding:

Installing package into ‘C:/Users/daniel/AppData/Local/R/win-library/4.5’
(as ‘lib’ is unspecified)

I have updated my RStudio more that ones, but still have issues

As the error says, you need to install Rtools - this is different to Rstudio and is not an R package (i.e. you can't install from R). Once you've installed Rtools, it should work.
