[R] sink() within a loop

[jgarcia at ija.csic.es]

Well, I'll put a foo example of my problem:

I'got a list:

>a <- list()
>a$sublist.1 <- list()
>a$sublist.1$subsublist.1 <- list()

this code works:

>zz <- file("foo.txt","w")
>sink(zz)
>a
>sink()
>close(zz)

and generates a correct "foo.txt" file containing the structure of the list

but this code doesn't:

>for(i in 1){
 zz <- file("foo.txt","w")
 sink(zz)
 a
 sink()
 close(zz)
}

as the resulting "foo.txt" file is empty

I don't understand why.
