[R] How to use Rpad

Wed Feb 14 19:50:41 CET 2007

I am a beginner and I don't know how to use Rpad package. 
I installed it and opened the following example .Rpad page in Internet
Explorer.
When I clicked "Calculate" button, nothing seems to happen. Can anyone tell
me how to use Rpad?

dataset = iris

<p>Now lets do some fancy HTML output: <span contenteditable="false">

<p>Here is a simple distribution plotting example with a lognormal
distribution with meanlog=10 and variable logsd:</p>

      <p><span contenteditable="false"><input class="Rpad_input" name=

      Standard deviation<br></p>

HTMLon()
showgraph()

<p>Here is another graphic: </p>

      border = NA, box = FALSE)
HTMLon()
showgraph()
