append_attr: Add a module to a 'moduleList'

append_attrR Documentation

Add a module to a moduleList

Description

Ordinary base lists and vectors do not retain their attributes when subsetted or appended. This function appends items to a list while preserving the attributes of items in the list (but not of the list itself).

Usage

append_attr(x, y)

## S4 method for signature 'list,list'
append_attr(x, y)

Arguments

x, y

A list of items with optional attributes.

Details

Similar to updateList but does not require named lists.

Value

An updated list with attributes.
