[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 features (eg some 1000 and more - 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
