I am having issues importing data from a .csv file input, and then filtering the date from that file. If I hardcode the file using data_input <- read.csv('Testy.csv'), the app runs smoothly. However, if I use fileInput to select the same Testy.csv file, it gives me Error: no applicable method for ‘filter’ applied to an object of class “c(‘reactiveExpr’, ‘reactive’, ‘function’)”.
