How to engineer an app? Data pipeline as follows:
Empty data frames
Input is .csv (uploaded daily)
Functions to calculate values from .csv
values to existing data frames. Updates and saves empty data frames.
I do have all the code that works on local computer given filenames for read.csv. Also have created flexdashboard in R Markdown as output.
Data frames are calendar months. Input needs to be file upload via dashboard. What are possible solutions? What about hosting? Needs to be accessed via web and needs to keep updated tables.
