Used to store an ordered collection of elements of the differnt data type.
We use list() Function to inset the elemnts.
We can access the list with index number inside a [] bracket.
Functions are a built in methods that performs operations fast and easy.

Description
Example
Length
length(vec)

element_names <- names(my_list)
Checking Element Existence
%in%

exists <- "new_element" %in% names(my_list)
Converting List to Data Frame
as.data.frame()
Converts a list to a data frame.
df <- as.data.frame(my_list)
my_list <- list(7, "eight", TRUE)
my_list
length(my_list)
element_exists <- "new_element" %in% names(my_list)
element_exists
df <- as.data.frame(my_list)
df
