[R] Get the output of a function in R GUI

[Jesús Para Fernández]

Hi,

I want to create my own RGUI, so I´m using tcltk for that. 

In a very simple example, I want to get the response of a function into a tktext, so I have done this:
data<-c(2,3,5,2)
tt<-tktoplevel
text<-tktext(tt)
tkpack(text)
sum(data)

How can I get the output of sum(data) in my tktext??

Thanks!
Jesús
