PR fix-eda addresses:
- You are only including systems that were produced after 2010, but excluded 3DS and PC games. I think you were just going for console platforms, but also included the PSVita (maybe you thought this was Playstation 5), in which case the 3DS and PC could be included. You're right, I misstook "PSV" to mean "PS5". However, I don't think it would be an issue to include portables and PC. New PR includes 3DS, PC Games

What are the units for the mean sales platform tables?
Millions of units sold. The aggregate() function calculates the mean for the columns but the units remain the same
-
I already mentioned the total_sales_genre not existing when trying to knit
Removed and refactored this section to be more simple
-
Are we going to remove observations with year of NA? I would think so right?
Fixed; Removed < 2% of dataset where Year was "N/A" and cast Year to numeric datatype
-
It looks like there are very little observations after the year 2016 (less than 5), which is why the total_sales_year plot makes it look like the market crashed in 2017. No big deal but we can say the data is from 2010 to 2016 instead
concur, we now filter the dataset at the very beginning to remove observations after 2016
