Here we are explaining how to write an R program to create a blank or empty matrix. For a better understanding of this R program example, we always recommend you to learn the basic topics of R programming listed below:
Here we are explaining how to write an R program to create a blank matrix. 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 blank matrix. 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 6 rows with 5 columns
STEP 3: Create by calling like matrix(, nrow = 6, ncol = 5)
STEP 4: print the result matrix
Matx=matrix(, nrow = 6, ncol = 5) print("Empty matrix of 6 rows and 5 columns:") print(Matx)
 "Empty matrix of 6 rows and 5 columns:" [,1] [,2] [,3] [,4] [,5] [1,] NA NA NA NA NA [2,] NA NA NA NA NA [3,] NA NA NA NA NA [4,] NA NA NA NA NA [5,] NA NA NA NA NA [6,] NA NA NA NA NA
