You first example is a list of 5 items, each item is a number
The second example is a list with one item: a vector with 5 elements.
You'll need c() to make a vector of the item to get the same result.
all.equal(list(c(0.8,0.9,1.0,1.1,1.2)), list(seq(0.8, 1.2, by = 1.1)))

To call in the statistician after the experiment is done may be no more than
asking him to perform a post-mortem examination: he may be able to say what the
experiment died of.

The combination of some data and an aching desire for an answer does not ensure
that a reasonable answer can be extracted from a given body of data.

Onderwerp: [R] newbie: embeding seq in a list
Suppose I want to create a structure containing the following values:
0.8,0.9,1.0,1.1,1.2
If I use
env <- list(0.8,0.9,1.0,1.1,1.2)
then R returns
> env
[[1]]
[1] 0.8
[[2]]
[1] 0.9
[[3]]
[1] 1
[[4]]
[1] 1.1
[[5]]
[1] 1.2
But, if I try to 'save some key-strokes', and use
env <- list(seq(0.8,1.2,by=0.1))
then R returns
> env
[[1]]
[1] 0.8 0.9 1.0 1.1 1.2
I'd like the 'latter' to be equivalent to 'the former', but
can't figure out how to achieve said aim.
Thanks in advance...
