In baslat/sak: The Swiss Army Knife of R

Extract elements from a list by name

Description

This function takes a list and a name, and recursively returns all elements in the list that have a name matching the provided name. The matching is done using the grepl function with fixed = TRUE, which means that the name is matched exactly, without any regular expressions.

Usage

extract_by_name(x, name)

Arguments

x	A list from which to extract elements.
name	The name of the elements to extract.

Details

The function first unlists the input list using the unlist function. It then uses the grepl function to find all elements in the list that have a name matching the provided name. The fixed = TRUE argument to grepl means that the name is matched exactly, without any regular expressions. The matching elements are then returned as a vector.

Value

A vector of elements from the list that have a name matching the provided name.

Examples

list_data <- list(a = 1, b = 2, c = 3, d = 4)
extract_by_name(list_data, "a") # returns 1
