# Unlike `@`, this operator extracts attributes for any kind of
# objects:
factor(1:3) %@% "levels"
mtcars %@% class
mtcars %@% class <- NULL
mtcars
# It also works on S4 objects:
.Person <- setClass("Person", slots = c(name = "character", species = "character"))
fievel <- .Person(name = "Fievel", species = "mouse")
fievel %@% namePlease choose more modern alternatives, such as Google Chrome or Mozilla Firefox.
