How to Create Ones Matrix in R - Step by Step Examples
How to Create Ones Matrix in R ?
Answer
In R, you can create a ones matrix by using the matrix()
function and specifying the number of rows and columns. You can initialize all elements to one by providing the value '1' as the argument.
✐ Examples
1 Creating a 3x3 Ones Matrix
In this example,
- We use the
matrix()
function to create a 3x3 ones matrix. The argumentsnrow
andncol
specify the number of rows and columns in the matrix, respectively. - We assign the resulting ones matrix to a variable named
ones_mat
. - We print the
ones_mat
to the console to verify the creation of the ones matrix.
R Program
ones_mat <- matrix(1, nrow = 3, ncol = 3)
print(ones_mat)
Output
[,1] [,2] [,3] [1,] 1 1 1 [2,] 1 1 1 [3,] 1 1 1
2 Creating a 2x4 Ones Matrix
In this example,
- We use the
matrix()
function to create a 2x4 ones matrix. The argumentsnrow
andncol
specify the number of rows and columns in the matrix, respectively. - We assign the resulting ones matrix to a variable named
ones_mat
. - We print the
ones_mat
to the console to verify the creation of the ones matrix.
R Program
ones_mat <- matrix(1, nrow = 2, ncol = 4)
print(ones_mat)
Output
[,1] [,2] [,3] [,4] [1,] 1 1 1 1 [2,] 1 1 1 1
