Thanks for your time and efforts :-)
That's useful.

I would like to precise that to get a functional shiny app as yours, we should use add the following outputs in the ui's main panel:

tableOutput("filedf"),
tableOutput("filedf2"),
textOutput("fileob"),
textOutput("summ"),
tableOutput("table")

Hi Mr Abhinav, thank you for uploading these videos. I would like to know how can I increase the file size to upload.

What's the difference between datapath and data tags? If we can have the datapath with input$file, why do we still need input$file$datapath to get the same path?

Hey Abhinav,
I have one question, is it possible to be able to upload various folders in a shiny app, render the names of those folders to a drop-down menu in the app. And then select the csv files for plotting from those folders directly on the app's user interface.


Thank you.

Hello Abhinav, thank you for uploading all these videos, your videos are helping me a lot for my project works. I am facing an issue, I tried inserting a .csv file into the upload file and it worked. My question is that in my .csv data one column contains date field, and it is showing the structure as "factor" but I want it to be in "date" format to plot a time series. How to convert to date format if we are uploading the file directly into shiny upload file area?

Hi Mr Abhinav, thank you for uploading these videos, they are very beneficial especially for beginners including me.
If i want to:
1) carry out computations on the uploaded csv file
2) download the results in csv format
as the extensions to what you did in this video, how should I change the code?

End of this video is quite abrupt, is that the end of the code? or is there more to it?
