Obtaining the dimension of a matrix
To obtain the dimension of a matrix in R, we use the dim() function.
Syntax
dim(matrix)
Parameter
The dim() function takes a single parameter, which is the matrix object.
Return value
The dim() function returns the dimension of a matrix passed to it.
Example
# creating a matrixmymatrix <- matrix(c("apple", "banana", "cherry", "orange"), nrow = 2, ncol = 2)# implementing the dim() functiondim(mymatrix)
Explanation
We create 2x2 matrix (a matrix with 2 rows and 2 columns) mymatrix. Using the dim() function, we check for the dimensions of the matrix. As we can see from the output, it is a 2x2 matrix.
