[R] Execute R without environment and multiple grid in multiple graphics

[solares@unsl.edu.ar]

hello, i like execute a script in R without having to execute the 
environment R, my scrip uses the package tcltk,
for ej :
global var
myfunction<-function(){
tt<-tktoplevel()
b<-tkbutton(...)
..}
I want that the interfaz is only seen, and that it shows objects of R, for 
example graphics without the environment
of R so much in windows (perhaps making click in ujn icon or executing one 
lines of commands) like in linux.
And another question is i cant work in multiple axis "y" with multiple 
grid, how i cant make this?
Thanks Ruben.
