Html submissions and speedgrader

[ztreisman]

My students submit assignments in html format - it's output from RMarkdown. The speedgrader doesn't appear to give me the option to mark up or add inline comments to the assignments. Am I missing something or is Canvas?

.html  files are not one of the formats supported for rendering in DocViewer.

What types of files can be previewed in Canvas? 

behind the scenes docviewer works by converting supported files to PDF and then rendering the PDF with the markup  tools. An alternative solution would be to have students submit a PDF version.

It looks like RMarkdown natively supports exporting to PDF (3.3 PDF document | R Markdown: The Definitive Guide ) but if that doesn't work you can always open the HTML file in a brower  and save it as a PDF.
