Hi again,
The unz connection is non-blocking by default. I checked do_unz which calls
R_newunz which calls init_con and the only place in any of those functions that
sets 'blocking' is init_con which sets it to FAL

Hi,
you could use "scan" instead, it seems to work fine also when wrapped
around "unz".
Or, alternatively, you could use "unzip" instead of "unz". It works as
expected, i.e. reads the last incomplete line and throws a warning about
this.
So it seems to me that "unz" creates a non-blocking con

Dear list,
I'm seeing a strange interaction with readLines() and unz() when reading
a file without an empty final line. The final line gets dropped silently:
> cat("hello", file = "hello.txt")
> zip("hello.zip", "hello.txt")
adding: hello.txt (stored 0%)
> readLines(unz("hello.zip", "hello.txt"

I leave it to you and other wiser heads to figure out.
Cheers,

Hi Mikko,
I tried running a few different things, and it seems as though
explicitly using `open()` and opening a blocking connection works.
```R
cat("hello", file = "hello.txt")
zip("hello.zip", "hello.txt")
local({
conn <- unz("hello.zip", "hello.txt")
on.exit(close(conn))
