Error using GitHub actions with R markdown - r

Question

I'm new to using GitHub actions, so please be gentle with me! I'm trying to automate a script that I'm currently running using Windows Task Scheduler. I've written the yml code below and its stored (privately) on GitHub at jeremy-horne/Client/.github/workflows/
The RMD code is 900 lines long and works when run in R studio. It is stored on GitHub at jeremy-horne/Client
`
name: my_project
on:
schedule:
- cron: "18 17 */1 * *" # Every day at 18:17
jobs:
render-rmarkdown:
runs-on: ubuntu-latest
# optionally use a convenient Ubuntu LTS + DVC + CML image
#container: docker://dvcorg/cml:latest
steps:
- uses: actions/checkout#v3
- name: Setup R
uses: r-lib/actions/setup-r#v2
#- name: Setup Pandoc
# uses: r-lib/actions/setup-pandoc#v2
- name: Setup dependencies
run: |
R -e 'install.packages("renv")'
R -e 'renv::restore()'
- name: Identify and email articles
#env:
# repo_token: ${{ secrets.GITHUB_TOKEN }}
run: |
Rscript -e 'rmarkdown::render(input = "My_Markdown_Code.Rmd")'
if [[ "$(git status --porcelain)" != "" ]]; then
git config --local user.name "$GITHUB_ACTOR"
git config --local user.email "$GITHUB_ACTOR#users.noreply.github.com"
git add *
git commit -m "Auto update Report"
git push origin
fi
`
The error I get says "render-rmarkdown
there is no package called ‘rmarkdown’"
Any help much appreciated!
