...I have a loooiooong Rscript processing data on server activated by uploading a csv file to shiny web inteface.
Second, or same user can't fire script again until it's finished but I need to show how things are going.
Taking into account script is writing steps to a log file....is there any way I can show logfile contents IN REAL TIME via shiny?
I know I can tail the log and show latest rows but I would like a thing like tail -f bash command, showing in real time new lines
is that possible?
