Two things.
TASKS has
TASK: Naming with Numeric Values and "unlist"
STATUS: Open
FROM: <hornik@ci.tuwien.ac.at>
R> l <- list("11" = 1:5)
R> l
$11
[1] 1 2 3 4 5
R> unlist(l)
111 112 113 114 115
1 2 3 4 5
[ Bug or feature ? ]
This seems to be a feature (at least, SPLUS does the same), so please
close that task.
***
However, please add the following.
***********************************************************************
R> x <- rnorm(20)
R> y <- rnorm(20)
R> z <- lm(y ~ x)
R> typeof(z)
[1] "list"
R> unlist(z)
[[1]]
[1] 0.07030757
[[2]]
[1] -0.1790483
[[3]]
NULL
[[4]]
NULL
and many more ending in
[[152]]
NULL
[[153]]
NULL
[[154]]
NULL
***********************************************************************
This seems to be a BUG. SPLUS gives

etc etc
I haven't looked into the unlist code at all. Here's another problem.
***********************************************************************
R> l <- list(a = list(1:5, LETTERS[1:5]), b = "Z", c = NA)
R> l
$a
$a[[1]]
[1] 1 2 3 4 5
$a[[2]]
[1] "A" "B" "C" "D" "E"
$b
[1] "Z"
$c
[1] NA
R> unlist(l)
INTERNAL ERROR: ans_nnames = 10 ans_length = 12
Error: incorrect names vector length

Hmm ...
