# R Programming: Create an array of two 3x3 matrices each with 3 rows and 3 columns from two given two vectors

## R Programming: Array Exercise-4 with Solution

Write a R program to create an array of two 3x3 matrices each with 3 rows and 3 columns from two given two vectors. Print the second row of the second matrix of the array and the element in the 3rd row and 3rd column of the 1st matrix.

**Sample Solution** :

**R Programming Code :**

```
print("Two vectors of different lengths:")
v1 = c(1,3,4,5)
v2 = c(10,11,12,13,14,15)
print(v1)
print(v2)
result = array(c(v1,v2),dim = c(3,3,2))
print("New array:")
print(result)
print("The second row of the second matrix of the array:")
print(result[2,,2])
print("The element in the 3rd row and 3rd column of the 1st matrix:")
print(result[3,3,1])
```

Sample Output:

[1] "Two vectors of different lengths:" [1] 1 3 4 5 [1] 10 11 12 13 14 15 [1] "New array:" , , 1 [,1] [,2] [,3] [1,] 1 5 12 [2,] 3 10 13 [3,] 4 11 14 , , 2 [,1] [,2] [,3] [1,] 15 4 11 [2,] 1 5 12 [3,] 3 10 13 [1] "The second row of the second matrix of the array:" [1] 1 5 12 [1] "The element in the 3rd row and 3rd column of the 1st matrix:" [1] 14

**Previous:** Write a R program to create an 3 dimensional array of 24 elements using the dim() function.

**Next:** Write a R program to combine three arrays so that the first row of the first array is followed by the first row of the second array and then first row of the third array.
