[R] modifications to text.tree function

[Alexander Sirotkin]

Hi.

I have to make some minor modifications to the text.tree function - I
don't like the way it prints the split labels (they are too long in my
case and overlap). I tried to make s simple modification to the
text.tree function so that it will limit the number of significant
digits in tree labels, but could not - the original function uses some
undocumented "treeco" function, which I can not find.

Any ideas ? Thanks.
