R help - May 2008 - adjusting plot vs font size in a plot

Hello:

 

I am using plot() in rpart, making a decision tree plot. I use plot()
first, then text() followed, but I think due to the figure vs. text
size, the bottom of the text always gets cut off. I can only "see" the
text of the bottom of the tree if I make the font size REALLY small. 

 

I think is shouldn't be a specific rpart question, but rather a general
plotting technique question. 

 

Thanks,

Karen

It seems to be rather rpart specific, because exactly this is documented 
in ?plot.rpart:
use the argument "margin" in plot in order to add some more space for 
the text to the margins within the figure region.
