[R] convert 'list' to 'vector'?

[Liviu Andronic]

Dear all
How does one convert a "non-symmetric" list to a vector? See below:

> x <- list()
> x[[1]] <- letters[1:5]
> x[[2]] <- letters[6:10]
> x[[3]] <- letters[11:12]
> x
[[1]]
[1] "a" "b" "c" "d" "e"

[[2]]
[1] "f" "g" "h" "i" "j"

[[3]]
[1] "k" "l"

> paste(x)
[1] "c(\"a\", \"b\", \"c\", \"d\", \"e\")" "c(\"f\", \"g\", \"h\",
\"i\", \"j\")"
[3] "c(\"k\", \"l\")"
> as.vector(x)
[[1]]
[1] "a" "b" "c" "d" "e"

[[2]]
[1] "f" "g" "h" "i" "j"

[[3]]
[1] "k" "l"

> simplify2array(x)
[[1]]
[1] "a" "b" "c" "d" "e"

[[2]]
[1] "f" "g" "h" "i" "j"

[[3]]
[1] "k" "l"


What I would need to get instead is:
> letters[1:12]
 [1] "a" "b" "c" "d" "e" "f" "g" "h" "i" "j" "k" "l"

Any ideas? Regards
Liviu
