Hi Prof. Wise, The Sample1.xlsx averaged correlations for each year, rather than for each country in assignment description.

And should I remove double quotes in raw headers as sample2.tsv did.

Hi Prof. Wise, I found that sample2.tsv do not have any empty cells except Cantril Ladder score . But this feature is not mentioned in assignment description (or I should apologize for my neglect). I wonder if empty cells permissible in other columns...

Hi Prof. Wise, I have a further question for the requirement I wonder which file should I base? The raw file or the merged file? Best regards, Kaichao Zheng

Hi Prof. Wise, I apologize for my unnecessary disturbing, Actually, the data is not missing, this is just a display error in Excel. Best regards, Kai Zheng

Hi Prof. Wise, The 33rd line in lab week9 original 151.csv seems missing, which should contains the type of pokemon Nidorino . This will cause trouble for merging files via paste . Best regard, Kai Zheng

Hi Prof. Wise, I'm so sorry to bother you. The directory for lab7 seems disappeared, even I update the local container by docker pull mjw263 cits4407 2024 v1 . I wonder if this is an error of my host or the docker server? Best regards, Kai Zheng

Hi Prof. Michael Wise It works. Thank you for your prompt handling. Regards, Kaichao

Today's (15 Apr) optional online test page has no content. Whether I missed it?

As a beginner, ChatGPT gives me an advice about using command wc. But our slides seem lack of relative introduction about wc, merely used it several times in demos.
