How to find Transpose of a Matrix in R


How to find Transpose of a Matrix in R ?

Answer

To find the transpose of a matrix in R, you can use the t() function. This function takes a matrix as input and returns its transpose.



✐ Examples

1 Transpose of a 2x2 Matrix

In this example,

  1. First, we create a 2x2 matrix named matrix1 using the matrix() function with a vector of values c(1, 2, 3, 4) and specify the number of rows as 2.
  2. To find the transpose of the matrix, we use the t() function on matrix1 and store the result in a new variable called transposeMatrix1.
  3. The t() function switches the rows and columns of the matrix.
  4. Finally, we use the print() function to display the transposed matrix stored in transposeMatrix1.

R Program

matrix1 <- matrix(c(1, 2, 3, 4), nrow = 2)
transposeMatrix1 <- t(matrix1)
print(transposeMatrix1)

Output

[,1] [,2]
[1,]    1    3
[2,]    2    4

2 Transpose of a 3x2 Matrix

In this example,

  1. We first create a 3x2 matrix named matrix2 using the matrix() function with a vector of values c(1, 2, 3, 4, 5, 6) and specify the number of rows as 3.
  2. To find the transpose of the matrix, we use the t() function on matrix2 and store the result in a new variable called transposeMatrix2.
  3. The t() function switches the rows and columns of the matrix.
  4. Finally, we use the print() function to display the transposed matrix stored in transposeMatrix2.

R Program

matrix2 <- matrix(c(1, 2, 3, 4, 5, 6), nrow = 3)
transposeMatrix2 <- t(matrix2)
print(transposeMatrix2)

Output

[,1] [,2] [,3]
[1,]    1    3    5
[2,]    2    4    6

3 Transpose of a 2x3 Matrix

In this example,

  1. First, we create a 2x3 matrix named matrix3 using the matrix() function with a vector of values c(7, 8, 9, 10, 11, 12) and specify the number of rows as 2.
  2. To find the transpose of the matrix, we use the t() function on matrix3 and store the result in a new variable called transposeMatrix3.
  3. The t() function switches the rows and columns of the matrix.
  4. Finally, we use the print() function to display the transposed matrix stored in transposeMatrix3.

R Program

matrix3 <- matrix(c(7, 8, 9, 10, 11, 12), nrow = 2)
transposeMatrix3 <- t(matrix3)
print(transposeMatrix3)

Output

[,1] [,2]
[1,]    7    10
[2,]    8    11
[3,]    9    12
