Here we are explaining how to write an R program to create a matrix taking a given vector of numbers as input. Here we are using a built-in function matrix() for this conversion. This method helps to creates a matrix from the given set of values. The syntax of this function is,
matrix(data = NA, nrow = 1, ncol = 1, byrow = FALSE,dimnames = NULL)
NA: An optional data vector.
nrow: The desired number of rows.
ncol: The desired number of columns.
byrow: If FALSE (the default) the matrix is filled by columns, otherwise filled by rows.
dimnames: NULL or a list of length 2 giving the row and column names respectively.
Below are the steps used in the R program to create a matrix taking a given vector of numbers as input. In this R program, we directly give the values to built-in functions. And print the function result. Here we used variables Matx for assigning matrix.
STEP 1: Assign variable Matx with matrix values
STEP 2: Create a matrix of 12 elements with 3 rows
STEP 3: Create by calling like matrix(c(1:12), nrow = 3, byrow = TRUE)
STEP 4: print the result matrix
Matx = matrix(c(1:12), nrow = 3, byrow = TRUE) print("Original Matrix is:") print(Matx)
 "Original Matrix is:" [,1] [,2] [,3] [,4] [1,] 1 2 3 4 [2,] 5 6 7 8 [3,] 9 10 11 12
