append_attr: 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 list,list
append_attr(x, y)

Value

An updated list with attributes.

Arguments

x, y

A list of items with optional attributes.

Author

Details

Similar to updateList but does not require named lists.

Examples

tmp1 <- list("apple", "banana")
tmp1 <- lapply(tmp1, `attributes<-`, list(type = "fruit"))
tmp2 <- list("carrot")
tmp2 <- lapply(tmp2, `attributes<-`, list(type = "vegetable"))
append_attr(tmp1, tmp2)
rm(tmp1, tmp2)
