From shiny, display pdf output in new browser tab?

[Norman Packard]

I sometimes have graphics output (e.g. many graphs) that is best compiled and displayed in a pdf.  I would like to generate such a pdf from within shiny, then display it in a new browser window / tab using the browser's default pdf viewer.

I found Joe Cheng has given one approach to displaying a pdf by putting it in the  www directory (e.g. called output.pdf) and using a call like tags$iframe(src="output.pdf", width="600", height="900").  I have tried this, and it works quite well. It even works within a renderUI call in server.R, where the filename can be changed dynamically.

But... it doesn't have some nice features of using the browser's pdf displayer, e.g. saving to a file.

I tried replacing the tags$iframe with straight HTML, trying to pop up a new window:

HTML(paste0('<a href=http://localhost:3838/output.pdf target="_blank>" Click here for the results...</a>'))

but this didn't seem to do anything.

Thanks for any help!

Never mind.  The tags$iframe() solution actually does use the default browser pdf viewer.  I just wasn't mousing to the right place to see the buttons.

Your <a href> would've worked too--there's just a double-quote on the wrong side of the bracket. Also it's much easier to do:

a(href="output.pdf", target="_blank", "Click here for the results...")
