Thanks Joris, it makes sense now, though the doc is a bit misleading.

Hi Karl,
that is expected. The moment you close a connection, it is destroyed as
well (see ?close). A destroyed connection cannot be tested. In fact, I've
used isOpen() only in combination with the argument rw.

[1] FALSE
cheers
On Thu,
Hello,
>From the doc, it says:
"isOpen returns a logical value, whether the connection is currently open."
But actually it seems to die on closed connections:
> con <- file()
> isOpen(con)
[1] TRUE
> close(con)
> isOpen(con)
Error in isOpen(con) : invalid connection
Is it expected ?
Tested on R
