Loading epoxy into devcontainer

[brtarran]

I've built a Quarto report that uses epoxy. It renders fine locally. I wanted to test this out in a GitHub Codespace, but I've been having trouble loading in epoxy as part of the codespace setup.

In my devcontainer file, I have:

"ghcr.io/rocker-org/devcontainer-features/r-packages:1": {
            "packages": "github::rstudio/renv,tidyverse,readxl,dplyr,janitor,reactable,here,ggplot2,plotly,scales",
            "additionalRepositories": "epoxy = 'https://gadenbuie.r-universe.dev'"
        }

However, when I run the qmd file, I get an 'epoxy not found' error unless I run a separate install using:

install.packages("epoxy", repos = c('https://gadenbuie.r-universe.dev', 'https://cloud.r-project.org'))
library(epoxy)

I'm sure this is probably user error, but if anyone can advise on resolving this issue I'd be grateful.
