change 'breaks' argument of hist() function with R

Question

I want to do the following :

• Open a window (easy with tcl/tk)
• add " breaks " field, " apply " button, and " accept " button to the window (easy too)
• loop while i < nbFiles
  • read file i (easy)
  • display an histogram of the data in current file in the window (need help)
  • user can provide breaks argument of hist() function in the field, and once he pushes apply button, new histogram with that configuration will be displayed in the window (need help)
  • wait for accept button to be pushed (Need help) >> histogram will be saved in a file (easy)
  • close the window (easy)

Is it possible ? can I do that with R and tcl tk ? An idea ? thanks

tkrplot can do that too

histo <- tkrplot(tt, function()hist(data)
