The user should be able to select which of the columns they wish to see on a plot and these plots should have the Date the first column in the dataframe on the x axis and the expenditure data on the y axis.

The data is always saved to a temporary directory and given a temporary name. I think the easiest way to understand this data structure is to make a simple app. Run the following code and upload a few files to get a sense of what data Shiny is providing.

You can see the results after I uploaded a couple of puppy photos from Section 7. Figure 9. The accept argument allows you to limit the possible inputs. Section 8. Putting all these ideas together gives us the following app where you can upload a.
