### How to extract all elements except the 3rd one of the first vectors of a list

Here we are explaining how to write an R program to extract all elements except the 3rd one of the first vectors of a 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

### How to extract all elements except the 3rd one of the first vectors of a list using the R program

Below are the steps used in the R program to extract all elements except the 3rd one of the first vectors of a 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. Extract all elements except the 3rd one of the first vector as like L1$$g1 = L1$$g1[-3]. Finally, print the vector value.

### ALGORITHM

• STEP 1: Assign variables L1 with a list
• STEP 2: Create L1 with 3 sets of elements g1,g2,g3
• STEP 3: Print the first vector
• STEP 4: First vector without the element is extract by L1$$g1 = L1$$g1[-3]
• STEP 5: Print the final vector value

### R Source Code

L1 = list(g1 = 1:5, g2 = "C Programming", g3 = "JAVA")

print("Original list:")
##  "Original list:"
print(L1)
## $g1 ##  1 2 3 4 5 ## ##$g2
##  "C Programming"
##
## $g3 ##  "JAVA" print("First vector:") ##  "First vector:" print(L1$g1)
##  1 2 3 4 5
print("First vector without third element:")
##  "First vector without third element:"
L1$g1 = L1$g1[-3]
print(L1\$g1)
##  1 2 4 5
