In my job, I use R to do analysis for something my colleagues use 4-6 desktop apps for - I also do this in a fraction of the time. I have given in trying to convince them to learn R. I'm now considering wrapping this up in a web-based package for non-coders. The question is this:
What's the best way to do it?
This doesn't have to be pretty but it must have the ability to upload data from multiple files from their desktops and then display various text, slider and dropdown menus that manipulate that data to produce a series of data visuals. While this is accessible to hundreds of staff, no more than 10 people at a time will be using this with datasets that are not huge.
Shiny looks like a good bet but I am wondering whether it's worth starting from scratch and learning HTML, CSS, and/or JS?
