UK broadband speeds - embedding Tableau dashboards into Rmd files

I found a new dataset on UK broadband speeds and started analysing it in R. Once the data was cleaned, though, building a dashboard in Shiny looked like it would take too long, so I switched to Tableau. To keep everything in one place, I embedded the dashboard into the output HTML document (below).

At first I assumed R Markdown couldn’t render embedded Tableau visualisations, because the iframe looked blank straight after knitting. It turned out I just had to open the generated file in a browser to see the iframe fill up with the Tableau dashboard.

The R Markdown file is available here.
