I have a problem. I am writing on my masterthesis and for my research question I have to use R-INLA. I tried to install the INLA-Package several times but there is an Error and it doesn't work.

https://www.r-inla.org/download-install When I try to install INLA like it is shown in the link, it doesn't work. I get some warnings, e.g.

"dependencies 'graph', 'Rgraphviz' are not available" or, second example: "Warning (...) file link "CRS"/"CRSargs" in packags "sp"/"rgdal" does not exist"

How can I deal with that? What can I do to solve this problems? I have no other choice, my professor wants me to use R-INLA for my thesis. I hope someone can help me, I am very desperate, tried so much but the problem still exists. Thank You!

  • The message says that `graph` and `Rgraphviz` are not available. Have you tried `install.packages(c("graph", "Rgraphviz"))`? – r2evans Feb 02 '21 at 12:53
  • Yes I tried, but that also doesn't work. Both packages are not available for my version of R – Olly_Queen Feb 02 '21 at 13:14

    *That* is your problem, not R-INLA. Neither of those packages appear to be on CRAN, one stating that it has been migrated to bioconductor. Are you certain that your `repos=` setting is correct to be able to install from their repo? – r2evans Feb 02 '21 at 13:17
  • did you look at the third paragraph/code box of the installation instructions? `if (!requireNamespace("BiocManager", quietly = TRUE)) { install.packages("BiocManager") }; BiocManager::install(c("graph", "Rgraphviz"), dep=TRUE)` – Ben Bolker Feb 02 '21 at 14:19
  • Thank you, I tried that but there is another problem: Matrix, rgdal and tibble have to be installed and installation of tibble failed – Olly_Queen Feb 02 '21 at 18:04
