Hmmm, system.file constructs a file path, it does not read the contents 
of a file. And you have constructed a non existant path, hence "" is 
reported.

Perhaps you rather want
txt <- readLines(c:\\text\\ABHANDLUNGXII.txt")

which is a guess given I do not know where that files really lives nor 
do I know the way you want to import the contents.

Best wishes,
Uwe Ligges
