问题
I am trying to create a RMarkdown document with RStudio using shiny server. It works fine if the ouptut is pdf but if I want it as html I get this following error at the end of the process (in the RMarkdown console I can see it reached 100%).
Error: unrecognized fields specified in html_dependency: attachment
I have no idea why this error is happening. Can anyone help me with this?
Thank you

This is caused by a recent update of the relevant rmarkdown package or related ones.
Update RStudio to the latest version and then the error should disappear. It worked in my case.

I had a similar problem and found that it was caused by RStudio attempting to use Knitr to build a Shiny page. You can fix this by running using rmarkdown::run() instead of rmarkdown::render(). In some older versions of RStudio, the "Knit html" button runs this:
rmarkdown::render('filename.Rmd', 'html_document')
whereas, you can get the the results you want by running this command instead:
rmarkdown::run('filename.Rmd')
You could use this command or just update to the latest version of RStudio.
There is more info about authoring Shiny document here: http://rmarkdown.rstudio.com/authoring_shiny.html.

Updating RStudio didn't work for me. What did work was updating all R packages (Tools > Check for Package Updates...).
