[R] playwith package does not work on Ubuntu?

[Ingo Michaelis]

Hello,

I try to use the interactive plot package playwith on my machine (Ubuntu 8.04 64
bit / Gnome) using R version 2.7.1. My problem is that the widgets are not
shown. I tried to plot the examples from the documentation, but it does not work
anyway. I tried on a WindowsXP machine and everything was ok.

So can you give me some advices
Thanks in advance
