I am seeing similar problem with using includeHTML(rmarkdown::render("myMarkdown.Rmd")). It messes up other panels. Is there an option to include body only.

Basically, I want to allow user to load a file and obtain a report in html. RMarkdown seems a natural choice, as it can be run and generate a HTML or PDF file the users can print or download. However it seems to interfere with other panels.

Any help is appreciated.

Sorry, I meant includeHTML(knitr::knit2html("About.Rmd", fragment.only = TRUE)).

Basically you can put withMathJax() in any UI functions that has the
... argument, e.g. tabPanel().

I should add that when includeHTML is used, the file loader failed to work.

I have this same issue. Using "includeHTML" is breaking my upload box (and causing other issues). I'll be trouble shooting this all tomorrow and I'll report back if I find a solution.

Just an update in case someone is reading, Apparently this only happens when you have a html document embedded inside a shinydashboard tabpanel. I was able to fix the issue by manually removing the head part of my html file (everything between <head> and </head> and only including the body). Will try to figure out more soon.

Looking forward to hearing your progress. I would like to use somethign like this includeHTML(rmarkdown::render("myMarkdown.Rmd")) if there is an option to include only the body.

Maybe we could render Markdown in one step followed by removing the head section, and then feed to includeHTML. That seemed to work OK. Now the problem is that includeHTML("myMarkdown.html") in ui.R does not get the newly generated html file.

Combined with using renderUI to provide the html file to ui as suggested by http://stackoverflow.com/questions/24875943/display-html-file-in-shiny-app seems to solve my problem!

Works very well if I delete everything outside the <body> and <\body>. Thank you so much!
