Re: [R] How to make labels on my dendrogam look more clear and visible

I feel a bit timid in asking this question: Why create the PS? Why not create the pdf directly?

?pdf

You have lots of control over the size and other characteristics, and the pdf can be used by MiKTeX to create a TeX -> pdf document containing your graphic.

I'm running R 2.2.0 on a DELL WinXP machine.

I don't know if it'll help, but I've grown fond of postscript graphs.

For example...

> postscript("mydendogram.ps", height=800, width=2000, pointsize=[????])
> plot(mydendogram)
> dev.off()

gives me very clear print, and then the ps2pdf app can turn it into a pdf for e-mailing or import to a presentation.
