π in R

I think I'm pretty much doing pi approximations in every language now, so, here it is in R!

I was going to do NASM before R (and actually before Raku Haskell even), but ran into some issues with floating point numbers that I'm currently working on fixing (if you know how to fix it, please tell me here: https://repl.it/talk/ask/NASM-Print-Floating-Point/41105).

Here are the other approximations so far:
Haskell - https://repl.it/talk/share/p-in-Haskell/41199
Raku - https://repl.it/talk/share/p-in-Raku/41111
Rust - https://repl.it/talk/share/p-in-Rust/41056
Go - https://repl.it/talk/share/p-in-Go/40950
Swift - https://repl.it/talk/share/p-in-Swift/36150
C# - https://repl.it/talk/share/p-in-C/36141
Bash - https://repl.it/talk/share/p-in-Bash/36133
Kotlin - https://repl.it/talk/share/p-in-Kotlin/36125

Credit to @NoelBryan, @TheForArkLD , @Warhawk947 , and @LizFoster for inspiring these approximations. Most of these use the Nilakantha Series, although I also use the arctangent method (multiplying the radian arctangent of 1 by 4 to get pi and getting the arctangent with an infinite series) in three of them (Python, Node, and C).

Also, credit to @HahaYes for inspiring this approximation in R!

Next up is NASM (Assembly; only if I can actually figure it out. I might have to save it for later since it is so difficult to program in. I keep pushing it back anyways due to issues with printing floating point numbers), followed by Dart. If you have any suggestions for after those, please let me know!

@awesome10 it took 25 years of programming experience to make that
