## 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

``````list(…)
```
```

Where ....(dots)are the objects, possibly named.

## 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:")
print(L1)
print("First vector:")
print(L1\$g1)
print("First vector without third element:")
L1\$g1 = L1\$g1[-3]
print(L1\$g1)```
```

## OUTPUT

``` "Original list:"
\$g1
 1 2 3 4 5

\$g2
 "C Programming"

\$g3
 "JAVA"

 "First vector:"
 1 2 3 4 5
 "First vector without third element:"
 1 2 4 5```
