R help - Mar 2010 - Placing the legend 'dynamically'

Hello,

does anybody know which command to consider when I'm trying to plot a  
stacked barplot with a legend at the most empty portion of the graphic?
I've searched for it, and somebody stated to use the labcurve-command,  
but I don't know how to produce stacked barplots with it.
Is there any possibility to plot a legend box "dynamically" (= in an  
empty region) with the legend()-command?
That would be helpful, because I'm already using this one.

Thank you,

Kind regards, Tom

Hi tom,
have a look at the emptyspace-function from the plotrix package. Looks 
like it does what you want?!

Hi Tom,
As Eik mentioned, you can use the emptyspace function. This works most 
of the time, and there is also the locator function, used like this:

legend(locator(1),...)

allowing you to click where you want the legend to be placed.
