S7_data: Get/set underlying "base" data

In S7: An Object Oriented System Meant to Become a Successor to S3 and S4

Get/set underlying "base" data

Description

When an S7 class inherits from an existing base type, it can be useful to work with the underlying object, i.e. the S7 object stripped of class and properties.

Usage

S7_data(object)

S7_data(object, check = TRUE) <- value

Arguments

object	An object from a S7 class
check	If TRUE, check that value is of the correct type and run validate() on the object before returning.
value	Object used to replace the underlying data.

Value

S7_data() returns the data stored in the base object; ⁠S7_data<-()⁠ is called for its side-effects and returns object invisibly.

Examples

Text <- new_class("Text", parent = class_character)
y <- Text(c(foo = "bar"))
y
S7_data(y)

S7_data(y) <- c("a", "b")
y
