%>% vs |> Pipe Operator in R: Key Differences and Usage
%>% is the pipe operator from the magrittr package, widely used for chaining commands, while |> is the native pipe introduced in R 4.1.0. The native |> offers simpler syntax and better performance but lacks some advanced features of %>%.Quick Comparison
Here is a quick side-by-side comparison of the two pipe operators in R.
| Feature | %>% (magrittr) | |> (native) |
|---|---|---|
| Introduced in | magrittr package (before R 4.1.0) | R 4.1.0 (base R) |
| Syntax style | Function chaining with placeholder support | Simpler chaining, no placeholder support |
| Performance | Slightly slower due to package overhead | Faster, built into base R |
| Placeholder support | Yes, with . | No native placeholder |
| Compatibility | Requires magrittr or tidyverse | No extra packages needed |
| Advanced features | Supports pronouns, tee operator, and more | Basic piping only |
Key Differences
The %>% operator comes from the magrittr package and has been popular in the R community for years. It allows chaining multiple function calls in a readable way and supports a placeholder . to specify where the piped value goes inside the function call. This flexibility enables complex expressions and tidyverse-style data manipulation.
On the other hand, the native pipe |> was introduced in R version 4.1.0 to provide a lightweight, base R alternative. It uses simpler syntax and is faster because it does not rely on external packages. However, it does not support the placeholder ., so the piped value is always the first argument of the next function. This makes it less flexible but easier to learn and use for straightforward pipelines.
Another difference is that %>% supports advanced features like the tee operator %T>% and pronouns for referring to the left-hand side, which the native pipe does not have. Choosing between them depends on your need for these features versus simplicity and speed.
Code Comparison
library(magrittr) # Using %>% to chain functions with placeholder result <- mtcars %>% subset(cyl == 6) %>% transform(mpg2 = mpg * 2) %>% head(3) print(result)
|> Equivalent
# Using native |> pipe operator result <- mtcars |> subset(cyl == 6) |> transform(mpg2 = mpg * 2) |> head(3) print(result)
When to Use Which
Choose %>% when you need advanced piping features like placeholders, tee operator, or integration with tidyverse functions. It is ideal for complex data transformations and when you want maximum flexibility.
Choose the native |> pipe when you want a simple, fast, and dependency-free way to chain functions, especially for straightforward pipelines where the piped value is the first argument. It is great for base R users and when minimizing package dependencies.
In summary, use %>% for power and flexibility, and |> for simplicity and speed.
Key Takeaways
