Download & Install – INLA Project

Installation Guide

To install the stable or testing version of R-INLA, use one of the following commands in R:

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

To update INLA:

inla.upgrade() inla.upgrade(testing=TRUE)

Windows users may need to uninstall INLA before reinstalling. For required Bioconductor packages:


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

To install alternative Linux builds:

inla.binary.install()

Version Compatibility

Use the remotes package to install a specific version of INLA that matches your R version:

R 4.4	`24.05.10`	`remotes::install_version("INLA", version = "24.05.10", repos = c(getOption("repos"), INLA = "https://inla.r-inla-download.org/R/testing"), dep = TRUE)`

fmesher Dependency

From version 23.08.18, INLA depends on the fmesher package instead of a standalone binary. For more information, see fmesher on CRAN or the conversion guide.


options(repos=c(
  inlabruorg = "https://inlabru-org.r-universe.dev",
  INLA = "https://inla.r-inla-download.org/R/testing",
  CRAN = "https://cran.rstudio.com"
))
install.packages("fmesher")

Troubleshooting

Most installation issues arise from using outdated versions of R or INLA. Please ensure you are using:

The latest version of R (≥ 4.4 recommended)
The most recent INLA version from the repository

If issues persist, restart your R session and reinstall using the commands above.
