Making R 300x times faster!

Описание к видео Making R 300x times faster!

Someone came to me with some slow R code and asked if Rust could make it faster. Here is how I made their R code 300 times faster using Rust. After, someone schools me and makes the code 2000 times faster using base R and data.table. Sometimes an over emphasis on the tidyverse and data frames can make folks write slower code!
