R Shiny - dataset load in a first chunk doesn't exist in a second chunk …?
问题 I have a strange error in a shiny app I built with the library learnr . An error " Object not found " about an object I just loaded and just visualized (meaning the object exists no ?) Although I don't have a reproducible example, some of you will maybe understand what is creating the error : I have a first chunk {r load} that loads a dataset. There is no error here, I can even visualize the dataset (screenshot below) Then I have a second chunk, where I would like to manipulate the dataset.
