 Function | Description | Parameters | Example
 -------- | ----------- | ---------- | -------
-append() | Adds the second argument as additional columns to the first argument (note that the first argument is not over-written). Append is meant to be used in situations where one cannot use left-indexing. <br/> **NOTE: append() has been replaced by cbind(), so its use is discouraged.** | Input: (X &lt;matrix&gt;, Y &lt;matrix&gt;) <br/>Output: &lt;matrix&gt; <br/> X and Y are matrices (with possibly multiple columns), where the number of rows in X and Y must be the same. Output is a matrix with exactly the same number of rows as X and Y. Let n1 and n2 denote the number of columns of matrix X and Y, respectively. The returned matrix has n1+n2 columns, where the first n1 columns contain X and the last n2 columns contain Y. | A = matrix(1, rows=2,cols=5) <br/> B = matrix(1, rows=2,cols=3) <br/> C = append(A,B) <br/> print("Dimensions of C: " + nrow(C) + " X " + ncol(C)) <br/> The output of above example is: <br/> Dimensions of C: 2 X 8
 cbind() | Column-wise matrix concatenation. Concatenates the second matrix as additional columns to the first matrix | Input: (X &lt;matrix&gt;, Y &lt;matrix&gt;) <br/>Output: &lt;matrix&gt; <br/> X and Y are matrices, where the number of rows in X and the number of rows in Y are the same. | A = matrix(1, rows=2,cols=3) <br/> B = matrix(2, rows=2,cols=3) <br/> C = cbind(A,B) <br/> print("Dimensions of C: " + nrow(C) + " X " + ncol(C)) <br/> Output: <br/> Dimensions of C: 2 X 6
 matrix() | Matrix constructor (assigning all the cells to numeric literals). | Input: (&lt;init&gt;, rows=&lt;value&gt;, cols=&lt;value&gt;) <br/> init: numeric literal; <br/> rows/cols: number of rows/cols (expression) <br/> Output: matrix | # 10x10 matrix initialized to 0 <br/> A = matrix (0, rows=10, cols=10)
  | Matrix constructor (reshaping an existing matrix). | Input: (&lt;existing matrix&gt;, rows=&lt;value&gt;, cols=&lt;value&gt;, byrow=TRUE) <br/> Output: matrix | A = matrix (0, rows=10, cols=10) <br/> B = matrix (A, rows=100, cols=1)
