[R] newbie: embeding seq in a list

Pass a vector to list() instead of individual values:

> env <- list(c(0.8,0.9,1.0,1.1,1.2))
> env
[[1]]
[1] 0.8 0.9 1.0 1.1 1.2

Subject: [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...
