rmarkdown-action

Github action to render documents using rmarkdown. Uses rocker/r-rmd docker image which includes rmardkown, pandoc and latex.

Inputs

• input_file: path or name of input file, all with respect to root directory of the repo (e.g: my_doc.Rmd, path/to/my_doc.Rmd)
• output_format: (defaults to pdf_document), options are: word_document, html_document and pdf_document.

Outputs

• output_file: This is automatically generated as the name that precedes .Rmd + the output format extension (e.g: for my_doc.Rmd with output_format as pdf_document -> my_doc.pdf

Disclaimer: By default, the rmarkdown-action will simply render the document to desired format. If you also wish to upload the document back to the repo please see the later section

Example

name: Render documents with rmarkdown-action
on: [push]
jobs:
  render_document:
    runs-on: ubuntu-latest
    steps:
      - name: Set up Git repository
        uses: actions/checkout@v2
      - name: Render document
        uses: lc5415/rmarkdown-action@v1
        with:
          input_file: path/to/my_doc.Rmd
	  output_format: pdf_document

Other powerful usages

Uploading rendered document to GitHub

This makes use of the github-push-action to automatically upload the rendered document to the branch that trigerred the rmarkdown-action. This is useful when the quality of the rendering needs to be reviewed as well (which is almost always the case).

By default, the rendered document will be uploaded to the same location that the input file. If you want to be able to specify the output location please submit an issue.
