Hello,
after splitting a data-frame I want to access the results.
Maybe the problem is, that the factor/index is a string...
...or do I miss knowing details of the index-uasge?
Please look and help:

=======================================
How can I grab into the data-structures, using the indexing by
date-string and by the names like "host" and so on?
So: is it posisble to use split in a way, that the original index-names
("host", "status" and so on) can be used?
Ciao,
Oliver
