[R] plot.hclust with lots of objects

Dear all,

the default plotting method for hclust trees looks just fine for few
objects like in the 
example dataset. But when it comes to many objects (some 1000 - I'm
trying to visualize clustered microarray data) it renders a tree, that
one cannot inspect, because of overlapping text and lines. My question
is, is there a way or a plotting parameter for plotting a tree which is
wide enough to have all leaves separated and readable labels even for
that many objects? 
This would produce a very big image, so I think scrolling is essential.

I believe the answer is simple, but I'm unable to figure it out.

Thanks in advance
