ot; In the
current implementation, connections are a finite resource, and you need
to be able to get rid of them when you are done. close(con) is the way
to do that. If you want to re-open it, you need to remember the filename
(or extract it before calling close()), and issue another call to
should have posted would be
x <- cbind(1, c(9,7,9,3,7) )
and I'd still like the same output
duplicated(x)
[1] FALSE FALSE TRUE FALSE TRUE
duplicates(x)
[1] NA NA 1 NA 2

, all variables must be found in declared dependencies, the search
could stop before it got to globalenv(). But it seems unlikely that
your students are writing packages with namespaces.)

What is ETB? Your code is lo

I looked it up, and it has been like that since revision 2 when this
code was first committed to our repository in 1997. I imagine whoever
wrote it was following the pattern of some other language (maybe S), or
maybe just their own personal taste.

I'll
fix this in R-devel, and backport it to 2.13.0-patched.
