Hi,
By looking at a doc about ALTREP
https://svn.r-project.org/R/branches/ALTREP/ALTREP.html (by the way
congratulations for that and for R-3.5.0 in general), I was a little bit
surprised by the following example:
> x <- 1:1e10
> system.time(print(mean(x)))
[1] 5e+09
user system elapsed
Fixed in R-devel. I will port to R-patched after more testing.

Thanks for the report. A quick workaround before this gets fixed is to
add an extra first argument that has no space in it, e.g.
Rscript --vanilla "foo bar.R"
The problem exists

Hi Tomas,
Thanks for the info about the binary builds; I did install it, however the bug
still seems to be there in the current build. The workaround you suggested
does work:
C:\>"C:\Program Files\R\R-devel\bin\x64\Rscript.exe" "C:\foo bar.R"
Fatal error: cannot open file 'C:\foo': No such fil
Thanks, actually this is because the snapshot build is still one version
behind (74642, the fix is in 74643). When I build my own installer and
install it seems to be working fine. Sorry for the confusion,
Tomas

Serguei,
The R 3.5.0 release includes the fundamental ALTREP framework but does not
include many 'hooks' within R's source code to make use of methods on the
ALTREP custom vector classes. I have implemented a fair number, including
for mean() to use the custom Sum method when available, in the ALT
The issue is that readLines() tries to seek (for reasons I don't
understand) in the non-blocking case, but silently fails for "stdin"
since it's a stream. This confused the buffering logic. The fix is to
mark "stdin" as unable to seek, but I do wonder why readLines() is
seeking in the first place.
I suspect the reason for the seek is this:
cat("1\n", file = "foobar")
f <- file("foobar", blocking = FALSE, open = "r")
readLines(f)
#> [1] "1"
cat("2\n", file = "foobar", append = TRUE)
readLines(f)
#> [1] "2"
cat("3\n", file = "foobar", append = TRUE)
readLines(f)
#> [1] "3"
I.e. R can emul
Thanks for the clear explanation. At first glance seeking to the
current position seemed like it would be a no-op, but obviously things
are more complicated under the hood.

The issue was reported to me for https://github.com/randy3k/rtichoke/issues/50
which is a python program which embeds R and provides a interface to R.
With R 3.5, for reason which i don't understand, when I typed `"a"` in the
console
STDOUT got `"\x02\xff\xfea\x03\xff\xfe"` with the extra escaped
