Installation Error for INLA version 25.06.13 on Windows 11

[Prince Michael Amegbor]

Hi,

I'm running into an issue while trying to install the development version of INLA (25.06.13) on Windows 11 using the remotes package. I am using the latest version of R 4.5.1. I got the error below:

Downloading package from url: https://inla.r-inla-download.org/R/testing/src/contrib/INLA_25.06.13.tar.gz

It’s downloading the wrong file, why, I do t know.   It should download the windows binary.   You can go to …/R.  And locate the file and download and install manually

Thanks,   Håvard. I will do that.

That is strange, considering I am using the download code directly from the R-INLA page.

remotes::install_version("INLA", version = "25.06.13",
repos = c(getOption("repos"), INLA = "https://inla.r-inla-download.org/R/testing"), dep = TRUE)

Install_version is the issue, as it doesn’t understand it needs to get the binary build, not the source package. But that’s strange, since the docs says that the default on windows is not source. Take a look at the documentation, and set the type argument to something that tells it to get the binary package.
