How to create a matrix taking a given vector of numbers as input

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.

How to create a matrix taking a given vector of numbers as input in the R Program

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.

ALGORITHM

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

R Source Code

Matx = matrix(c(1:12), nrow = 3, byrow = TRUE)
print("Original Matrix is:")
print(Matx)

OUTPUT

[1] "Original Matrix is:"
[,1] [,2] [,3] [,4]
[1,]    1    2    3    4
[2,]    5    6    7    8
[3,]    9   10   11   12
