@icetianli would you be able to share some of the data you used for this tutorial?

[icetianli]

Yeah sure, will do.

I that the reason this is failing is becuase it is using ubuntu-latest but the latest distro of ubuntu on github is not having all the R dependencies as part of the image. i could be wrong.

[mnky9800n]

i still dont know why pkgdown fails. maybe @gareth-j knows.

Error: Error: processing vignette 'covid_mcmc.Rmd' failed with diagnostics:
parse error: premature EOF

i think there is something wrwong with the data download, but it does this for literally all of the tutorials.

@icetianli can you remove the .png files.

[gareth-j]

@icetianli can you change the header on the tutorial vignette to match the format of the other vignettes?
It'd be something like this:

---
title: "Simple Linear Regression with fdmr"
output: 
  bookdown::html_document2:
    base_format: rmarkdown::html_vignette
    fig_caption: yes
bibliography: "references.bib"
link-citations: yes
vignette: >
  %\VignetteIndexEntry{Simple Linear Regression with fdmr}
  %\VignetteEngine{knitr::rmarkdown}
  %\VignetteEncoding{UTF-8}
---

DESCRIPTION does not have tidyverse as an import, does it?

The pkgdown and ubuntu errors look similar to this StackOverflow question. The OP was also using Ubuntu.

Perhaps we have to have the xmatrix import in a different order?

@icetianli i cloned your repo and tried to run your tutorial and it fails when it tries to use the formula because fc is not declared.

I am guessing you are trying to use the data column FrontChange so when i replace fc with FrontChange I get this error:

tbh, i'm not sure what the id.loc0 variable is doing? it also is not declared. if you remove it, you can get inla to run:

Thanks all, will sort this notebook out asap.
