I have a number of shiny apps I've created for my introductory statistics class. Many of them are probably useful for other instructors/students as well.
They are currently hosted on my server at my university, https://pluto.coe.fsu.edu/rdemos/IntroStats/, although I have mirrored a couple of them at https://ralmond.shinyapps.io/.
I'm perfectly happy to share the source code (it is at common - Revision 1295: /rgroup-shiny/IntroStats.
How would I go about offering these as submissions to the Shiny gallery?
