Here we are explaining how to write an R program to assign new names to the elements of 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 assign new names to the elements of 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. Call the function list() with different types of elements. The function names() helps to get or set the names of an object.
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 names A,B,C to the element of the list as names(L1) = c("A", "B", "C")
STEP 5: Print the final list L1
L1 = list(g1 = 1:5, g2 = "C Programming", g3 = "JAVA")
print("Original list:")
print(L1)
names(L1) = c("A", "B", "C")
print("Assign new names 'A', 'B' and 'C' to the elements of the list")
print(L1)
[1] "Original list:" $g1 [1] 1 2 3 4 5 $g2 [1] "C Programming" $g3 [1] "JAVA" [1] "Assign new names 'A', 'B' and 'C' to the elements of the list" $A [1] 1 2 3 4 5 $B [1] "C Programming" $C [1] "JAVA"
