Hey, I tried this colClasses-option.
It's really fine! :)

Or use stringsAsFactors = FALSE,

No it doesn't - for the reasons given in my explanation.

Is this snormal behaviour?
Yes, it is. The idea is that a factor has a given set of levels
independent of how often you find them in your data - inclu

If they are changed to numeric, then the default printing results in
'911'. Can you provide a
