Hi,
Thanks for the answer and sorry about the confusion. I am not really sure myself about technically how the idea would work.
The idea would be to make the app so that people can edit it like people can edit a wikipedia page.
I don't think the shiny app should replace the general purpose web framework - I'm hoping more that the shiny app would bring all the statistical analysis possibilities to everyone. At the moment (as much as I know) all the statistical programs are quite complex and often not for free. I think R itself is too complex for many applications. But with this kind of a wiki with simple shiny apps offering statistical tools to everyone openly it would make things a lot easier for people.
I'm a chemistry PhD student and I see that these apps could be very useful for e.g. chemists or life scientists who need to do statistical analysis of their data. But the programs are complex and the statistics they need to use is complex - the result is that the scientists spend a lot of time studying statistics and the programs (and therefore not working on the topic they should be focusing on) and then it is still quite possible that the statistics is used in a wrong way (e.g. you can find numerous articles on how scientists often misinterpret the results of statistical tests because they don't understand quite correctly what the p-value they obtain means). That's the problem I'm hoping to solve with this wiki. Shiny apps could be made simple to learn and use, and quite foolproof so that results are not misinterpreted. And of course they can be made free for everyone.
I hope I clarified my question a little bit now.
All the best,
Hanno
