What version of R are you using? In 2.12.0 I get
> x <- 1:7
> y <- function(...)list(...)
> z <- runif(3) # creates .Random.seed also
> str(as.list(.GlobalEnv)) # add all.names=TRUE to get .Random.seed
List of 3
$ z: num [1:3] 0.698 0.475 0.354
$ y:function (...)
..- attr(*, "source")= chr "function(...)list(...)"
$ x: int [1:7] 1 2 3 4 5 6 7
> str(eapply(.GlobalEnv, function(x)x)) # all.names=TRUE ok here also
List of 3
$ z: num [1:3] 0.698 0.475 0.354
$ y:function (...)
..- attr(*, "source")= chr "function(...)list(...)"
h$ x: int [1:7] 1 2 3 4 5 6 7
Use environment() instead of .GlobalEnv if you want to
process the current environment.
In any version of R sapply() can give incorrect results,
as in (in a fresh vanilla R session):
> x <- 1:4
> y <- 11:14
> z <- 21:24
> str(sapply(ls(), get))
int [1:4, 1:3] 1 2 3 4 11 12 13 14 21 22 ...
- attr(*, "dimnames")=List of 2
..$ : NULL
..$ : chr [1:3] "x" "y" "z"
or, in another fresh session
> FUN <- "a string named FUN"
> X <- 17
> sapply(ls(), get)
$FUN
function (x, pos = -1, envir = as.environment(pos), mode = "any",
inherits = TRUE)
.Internal(get(x, envir, mode, inherits))
$X
[1] "FUN" "X"
as.list(envir) and eapply(envir, function(x)x) do
not have problems in those cases.
