This is really puzzling me and when I try to make a small example
everything works like expected.
The problem:
I got these two large vectors of strings.
> str(s1)
chr [1:766608] "0.dk" ...
> str(s2)
chr [1:59387] "043.dk" "0606.dk" "0618.dk" "0888.dk" "0iq.dk" "0it.dk" ...
And I need to create the union-set of s1 and s2.
I expect the size of the union-set to be between 766608 and 766608+59387.
However it is 681193 which is less that number of elements in s1!
> length(base::union(s1, s2))
[1] 681193
Any hints?
Regards
Martin
