Here we are explaining how to write an R program to add a new item to a given list. Here we are using a built-in function list() for this. This function helps to create a list. The syntax of this function is
list(…)
Where ....(dots)are the objects, possibly named.
Below are the steps used in the R program to add a new item to a given list. In this R program, we directly give the values to a built-in function list(). Here we are using variables L1 for holding the list elements g1,g2,g3. Call the function list() with different types of elements. Add the new item g4 with value 'Python' to the list L1 as like L1$g4 = "Python".
STEP 1: Assign variables L1 with a list
STEP 2: Create L1 with 3 sets of elements g1,g2,g3
STEP 3: Print the original lists
STEP 4: Add a new item g4 to the list as L1$g4 = "Python"
STEP 5: Print the final list L1
L1 = list(g1 = 1:5, g2 = "C Programming", g3 = "JAVA")
print("Original list:")
print(L1)
print("Add a new vector to the said list:")
L1$g4 = "Python"
print(L1)
[1] "Original list:" $g1 [1] 1 2 3 4 5 $g2 [1] "C Programming" $g3 [1] "JAVA" [1] "Add a new vector to the said list:" $g1 [1] 1 2 3 4 5 $g2 [1] "C Programming" $g3 [1] "JAVA" $g4 [1] "Python"
