First of all, please cut the trash talk, we like to keep things polite here, now to the business. You can't compare Stata with R, the former is a statistical software the later is a programming language, more comparable to Python, so you have to change your mindset when working with R and realize you are programming now so you need to pay attention to syntax, it actually is not that hard it just takes some time to get used to it.
I have made a reproducible example with a small subset of your data (this is what I was asking you to do when I asked for a reprex, you should read the guide I gave you if you want to learn how to properly ask for help here).
