I’m working on the project https://www.codecademy.com/courses/learn-r/projects/variance-in-weather-r .
I made it to step 2 with no problems, but the step 3 when I used the code to get a single column from a DataFrame as below didn’t work.
one_column <- london_data$column_name
I double-checked my code with what the hint suggested, and it’s exactly the same.
I even copied and pasted to make sure there wasn’t some tiny typo, and still the same result.
I had no problems so far but now I’m stuck. Can anyone figure out what the problem is? Is it a problem with my code, or a bug in Codecademy?
For reference, here is all the code I’ve done so far:
temp <- london_data$TemperatureC (didn’t work)
Tks so much
