Working with large data objects may make it harder to think about the problem. Use a quote character (‘) to start a comment. Although I have managed to load and then plot the data, when I tried to perform the Mann-Kendall test, I was getting this particular error every time which is really difficult to debug. of information out, but not much.

User Defined Functions (UDFs in short) are, as the name suggests, functions whose properties are custom defined by the user.
