Hi, I've got a really basic problem, but I have no idea how to solve it (new to R). Basically, I'm trying to read a CSV file with 2 variables, but RStudio just doesn't want to detect all the variables, so I can't do tables nor graphs or anything and that's super annoying because I don't understand the reason. The code works great for an excel file provided by my prof, but each time I modify this file, without changing its format, just the data in it, it's not working anymore. HELP.
