Here we explain how to write an R program to create an array using four columns, three rows, and two tables. Here we are using a built-in functions array(),dim() for this. The dim() function helps retrieve or set the dimension of an object and the array() function helps create the array. The syntax of this function is
dim(x) #Where x is an R object like a matrix, array, or data frame
array(data = NA, dim = length(data), dimnames = NULL) #Where data is a vector giving data to fill the array
Below are the steps used in the R program to create an array using given four columns, three rows, and two tables. In this R program, we give the values directly to an array(),dim(). Here we are using variable A for holding the result array. Here we are creating an array using the given data. Finally, print the array.
STEP 1: Assign array elements into the variable A
STEP 2: The array is created by using array(1:30, dim=c(3,5,2))
STEP 3: Print the array
A = array(1:30, dim=c(3,5,2))
print(A)
