Using pipes, such as the new native pipe in R, simplifies how functions appear in a code, easing the ability to intuitively debug a function

When a function is being created in a programming language, updates to that language can create new headaches in maintenance — a developer has to rewrite a section of code so that it is recognized. But in the case of R,

R 4.1 introduced a pipe operator symbol, |>. It is the first time a pipe has been incorporated as a base function. The change is small, but the impact of simplifying code is significant.

Memory Usage Report for RStudio (image: Pierre DeBois)

When RStudio introduced Version 1.4 of its popular IDE for R programming, a new debugging indicator was added called Memory Usage.

It is called Sanddance. …

Being a thought leader does not mean sharing an opinion on everything all the time

Seems like everywhere you look, someone wants to be a thought leader on some subject. Speaking out is meant to give an advantage in leadership and drawing attention to what you have to say. But with so much social media proving exposure to so many insights, it is really important to know what and when to contribute to a public conversation.
