set tkscale by tkentry
Hi, I am working under Windows and I am using R2.11

the scale to a certain specific value. Therefore I want to add tkentry to
allow the user to set tkscale to a certain value.
Here is the code
library(tcltk)
tt<-tktoplevel()
tkpack(m1<-tkscale(tt,from=306870.00, to=3026741, label="alpha",

Question about unicode characters in tcltk
hello list,
Can someone help me figure out why the following code doesn't work?
I'm trying to but both Greek letters and subscripts into a tcltk menu.
The code creates all the mu's, and the 1 and 2 subscripts, but it
won't create the 0. Is there a certain set of characters that R won't
recognize the unicode for? Or am I input the \u2080 incorrectly?

how to set up a slider in order to resize a set of pictures.

the setValue() function seem to work. Perhaps
