Issue creating a Shiny App: Input data+ plot specs (in csv) and Save Plots

Question

I am unable to create a Shiny App that:

1. Takes as input: datafiles and plot specifications in csv file format.
2. When pressing action button: runs all plots and saves them in a pre-specified folder (mentioned in the plot spec file) in a computer.
3. While plots are running, I would like to display just the progress bar to the user.

Can someone kindly guide on Shiny app structure.

PS: Apologize for posting a conceptual query and not sharing any specific codes.

Answer 1

First of all, you should learn about shiny with written tutorials from the official website. Then, you could use some tricks from advanced-shiny.

• 1) to upload a file you can check widget gallery from official shiny website here

• 2) You can check this stackoverflow post

• 3) you can check this code to show a wheel when loading, it will be a good start

Hope it helps to start!
