You can also create a 4×3 matrix using ncol. Note: Using command matrix_b <-matrix(1:10, byrow = FALSE, ncol = 2) will have same effect as above. Below is a syntax of R print matrix dimension: # Print dimension of the matrix with dim() Matrix_b <-matrix(1:10, byrow = FALSE, nrow = 5)Īgain, print the dimension of the matrix using dim(). Output: # 5 2 Construct a matrix with 5 rows that contain the numbers 1 up to 10 and byrow = FALSE # Construct a matrix with 5 rows that contain the numbers 1 up to 10 and byrow = FALSE The syntax to print matrix in R using dim() is: # Print dimension of the matrix with dim() Now, let’s print dimension of the matrix in R with dim().

Matrix_a <-matrix(1:10, byrow = TRUE, nrow = 5) # Construct a matrix with 5 rows that contain the numbers 1 up to 10 and byrow = TRUE Let’s construct two 5×2 matrix with a sequence of number from 1 to 10, one with byrow = TRUE and one with byrow = FALSE to see the difference. We use `byrow = FALSE` (default values), if we want the matrix to be filled by the columns i.e. byrow: The rows are filled from the left to the right.data: The collection of elements that R will arrange into the rows and columns of the matrix \.Following is a function to create a matrix in R which takes three arguments: matrix(data, nrow, ncol, byrow = FALSE) We can create a matrix with the function matrix(). Note: It is possible to create more than two dimensions arrays with matrix function in R. In other words, matrix in R programming is a combination of two or more vectors with the same data type. A matrix function in R is a 2-dimensional array that has m number of rows and n number of columns.
