R help - Sep 2003 - save object interactively

Hello, it wanted to know as I can keep to save a object of R in interactive 
form, in which I can put the name of the file in a window of I talk, and 
not to have to create it, a badly serious example:

 x<-c(1,2,3,4)
> nbre<-"x.Rdata"
> f<-file.choose()
Error in file.choose() : file choice cancelled
> f
Error: Object "f" not found
> file.create(nbre)
[1] TRUE
> f<-file.choose()
> save(nbre,file=f)
But I should create the file before electing it, there is not form of 
opening a window of I talk and to keep with a name that I can put in that 
window?  Does not something exist as 
file.choose.save?  . Thanks Ruben

The argument to the save function can be the result of a calculation,
so you could have

 save(nbre, file=file.choose())
