Getting URL Parameter with Rpad

[Rios]

Hi everybody.

I have the following question:

Is there some mechanism that permit to get the parameters passed in
the url?
Like this:

http://localhost/Rpad/freq.Rpad.shtml?id=35

I need to use the value of the variable "id" into the tag:

<pre dojoType="Rpad" rpadType="R" rpadRun="init"
rpadHideSource="true">
...
</pre>

The value of the variable "id" would be used in a function in R.

Cheers,
Ricardo
