Source: R/AllGenerics.R, R/elements.R
elements.Rd

Given TidySet retrieve the elements or substitute them.

Usage

elements(object)

elements(object) <- value

# S4 method for class 'TidySet'
elements(object)

# S4 method for class 'TidySet'
elements(object) <- value

replace_elements(object, value)

# S4 method for class 'TidySet,missing'
nElements(object)

# S4 method for class 'TidySet,logical'
nElements(object, all)

Arguments

object

A TidySet object.

value

Modification of the elements.

all

A logical value to count all elements or just those present.

Value

A data.frame with information about the elements

Methods (by class)

  • elements(TidySet): Retrieve the elements

  • elements(TidySet) <- value: Modify the elements

  • nElements(object = TidySet, all = missing): Return the number of elements
