magrittr
Improve the readability of R code with the pipe
The magrittr package provides pipe operators for R that allow you to chain function calls together in a left-to-right sequence, making code more readable by replacing nested function calls like h(g(f(x))) with x %>% f %>% g %>% h.
The package eliminates the need for temporary variables and nested parentheses when working with multiple sequential operations. It includes the main pipe operator %>%, a placeholder . for controlling where piped values are passed to functions, the ability to create reusable pipeline functions, and the %$% operator for exposing data frame variables to functions that don’t have a data argument. These features make it straightforward to add, remove, or reorder steps in data processing workflows.

Exploring Positron settings | Isabel Zimmerman & Davis Vaughan | Data Science Lab
The Data Science Lab is a live weekly call. Register at pos.it/dslab! Discord invites go out each week on lives calls. We’d love to have you!
The Lab is an open, messy space for learning and asking questions. Think of it like pair coding with a friend or two. Learn something new, and share what you know to help others grow.
On this call, Libby Heeren is joined by Posit engineers Isabel Zimmerman and Davis Vaughan as they share some of their favorite settings in Positron, a super customizable data science IDE. Come laugh with us as we can’t seem to figure out that VSCode calls rainbow parentheses “bracket pair colorization”
Hosting crew from Posit: Libby Heeren, Isabella Velasquez, Daniel Chen, Isabel Zimmerman, Davis Vaughan
