List is a type of an object in R programming. Lists can contain heterogeneous elements like strings, numeric, matrices, or even lists. A list is a generic vector containing other objects. Two-dimensional list can be created in R programming by creating more lists in a list or simply, we can say nested lists. The
list() function in R programming is used to create a list. In this article, we’ll learn to create plot graph using Two Dimensional List in R programming.
Creating a Two Dimensional list
A Two Dimensional list can be created with the use of
x: represents objects to be inserted in list
[] [][]  1 2 3 4 [] [][]  "A" "B" "C" "D"
Creating Plot Graph using Two Dimensional List
To create plot graphs, lists have to be passed as vectors to the
plot() function as coordinate values. The
unlist() function converts the list into an atomic type of vector.
