DATASET: Check that user supplied path exists before dispatch to R #536

Closed gjwgit closed 3 days ago

gjwgit commented 1 month ago

Description

The path to a filename that a user has typed in needs to be checked to make sure it exist before we attempt to ask R to load the file.

Here I have typed a path:

But the path does not exist. There should be a popup to say the path does not exist rather than simply attempting to load the file in R and silently failing.

This task requires refactoring the handling of CSV and TXT file loading. Currently there are several pathways and two scenarios (first load and loading when there is already a dataset loaded). Needs to be cleaned up and remove repeated coding.

The popup was implemented by Graham three weeks ago. I am currently working on refactoring the handling of CSV and TXT file loading.
