Pat I love your videos but in this one why you didn't use a loop from the get go? I saw all the way to the end but I think it doesn't make much sense to even show that kind of writing instead of mapping over the function or looping

Thanks for watching. My goal is to teach people how to program. Here my primary intention was to teach people how to access values in a matrix - not how to write a loop (re-read the title). Along the way, I wanted to help motivate the need for loops. By doing this all brute force it I was able to point out the problem with all the repetition, foreshadow the use of index variables (15:07), etc. I believe the next episode in the series then takes this code and converts it to a loop. There's even an episode that removes for loops entirely. I don't think it's fair to expect someone that has never seen a for loop before to understand the motivation for loops, the concepts, and how to implement them in under 20 minutes. I think I'm serving my audience well with this approach.

Good day, my R keeps saying "x" is not found, what could be the issue?

Hi - I'm not sure where you're getting this error in this episode. Usually that's because you haven't defined x earlier in the script
