[R] Why R GUI application so slow

[Zhesi He]

Hi, All,

I use RGtk and Rtcltk to build some graphical interface for 
bioinformatics data analysis applications.
I'm just wondering why the graphic display is so slow. For example, I 
tried to build a 2000 rows & 5 levels tree with both Rgtk and Rtcltk. 
RGtk cost about 15 seconds and Rtcltk about 10 seconds to load up...

Is there a fatser way to build such application? I have difficulty 
install RJava in my machine, is RJava faster in building the tree 
representation?

BTW, I'm using ibook G4 MacOS 10.3, R2.0

Many thanks.
