<h2>Array Variables</h2>
<p>
Sometimes you want to assign more than one value to a single variable. Then you can create a 
variable that can contain a series of values. This is called an array variable. The declaration of 
an array variable uses parentheses ( ) following the variable name. In the following example, an array containing
3 elements is declared:
</p>

<table width="100%" border="1" class="ex" cellspacing="0"><tr><td>
<pre>dim names(2)</pre>
</td></tr></table>

<p>
The number shown in the parentheses is 2. We start at zero so this array contains 3 elements. This is a fixed-size array.
You assign data to each of the elements of the array like this:
</p>

<table width="100%" border="1" class="ex" cellspacing="0"><tr><td>
<pre>names(0)=&quot;Tove&quot;
names(1)=&quot;Jani&quot;
names(2)=&quot;Stale&quot;</pre>
</td></tr></table>

<p>
Similarly, the data can be retrieved from any element using the index of the particular array element you want.
Like this:</p>

<table width="100%" border="1" class="ex" cellspacing="0"><tr><td>
<pre>mother=names(0)</pre>
</td></tr></table>

<p>You can have up to 60 dimensions in an array. Multiple dimensions are declared by separating
the numbers in the parentheses with commas. 
Here we have a two-dimensional array consisting of 5 rows and 7 columns:
</p>

<table width="100%" border="1" class="ex" cellspacing="0"><tr><td>
<pre>dim table(4, 6)</pre>
</td></tr></table>
