As assumed, this did not work.

But I found, where the problem might be located...


With a smalle testfile I tried this after
running my script:

===============================================
> levels(selected$host)
[1] "22.99.44.101"   "266.249.71.143" "5.66.61.230"    "66.29.1.13"    
[5] "7.6.1.20"       "7.6.14.240"

[1] "7.6.1.20"    "7.6.14.240"  "5.66.61.230"

===============================================

So, somehow there are unused levels inside.
Using drop=TRUE in split() did not helped.
So I have somewhere later to fix it.

But when I do it before tapply, there will be an error-message...
