First of all, although the question uses the term "list", the object named
'a' is clearly not a list as R defines the term. It is a vector.
Thus a better example answer is
a <- c('abc', 'def')
paste(a , collapse=' ')
and this works for however many elements there are in the vector a.
The example
a <- list("abc", "def", "ghi")
paste(a, collapse=" ")
works, but only because the paste() function first converts its arguments
to character strings.
I only mention this because it's important (especially for those new to R)
to understand the distinction between lists and vectors, even if they
occasionally appear to behave the same way. Consider this:
> a <- list("abc", "def", 3:6,"ghi")
> a
[[1]]
[1] "abc"
[[2]]
[1] "def"
[[3]]
[1] 3 4 5 6
[[4]]
[1] "ghi"
> paste(a, collapse=" ")
[1] "abc def 3:6 ghi"
And I did not expect that result, but something like this:
> unlist(a)
[1] "abc" "def" "3" "4" "5" "6" "ghi"
> paste(unlist(a), collapse=' ')
[1] "abc def 3 4 5 6 ghi"
