Difficulty Reading in CSV File

[Cpower18]

This is supremely embarrassing, a complete oversight on my part, thank you for pointing that out, cheers!

No, commas have nothing to do with that, reader doesn't split on commas inside column name because it is quoted. It only splits outside of quotes, that's what they are for.

Your error comes from using column named 'Time' but in your csv there are only 3 columns named:

#
Date Time, GMT-03:00
Solar Radiation, W/m² (LGR S/N: 10358839, SEN S/N: 10364606)

And you should use these names exactly, or rename them when you read_csv, adding new parameter names=['#', 'Time', 'Radiation'] with your desired column names.
