It seems like line 17 of your file does not have the same number of column as the previous one when they are separated using sep
You'll need to check that. Without anymore information it is difficult to help you
If you want further help, could you ask this with a minimal REPRoducible EXample (reprex)? A reprex makes it much easier for others to understand your issue and figure out how to help.
Hi, I tried the reprex package, and have read up on it. It sounds great - thank you for pointing me in that direction. However, I have received another error when trying to Render the Reprex.
Loading required package: shiny
Error in x[[n]] :
attempt to select less than one element in integerOneIndex
It seems like you are trying to render a shiny app in your reprex, this is not actually posible, try to isolate just the part of your code that is causing you troubles and put that in your reprex instead of the whole code (make sure to also provide sample data i.e. a csv file).
