Question

I need to import several files thanks to the technique:

I would like to retrieve the information of the number of files imported by the user. It is available somewhere because in the import tool, I can read "X files imported".

But how?

Answer 1

Once the files are uploaded (with fileInput("csvs", ....)), the paths of these files are located in input$csvs$datapath. Then the number of files is length(input$csvs$datapath).

See ?fileInput for more info about the contents ofinput$csvs.
