Happens with the Basic Data at the end of readConcData()
Warning in [<-.factor(*tmp*, is.na(DF$Result), value = 0) :
ungültiges Faktorniveau, NA erzeug
DF$Result[is.na(DF$Result)] <- 0
If an "ND" string was found in DF$Result, it becomes automatically a factor and this is when the error happens. Since the basic example contains "ND<.." elements, it will trigger but do no harm because no NA fields exists.
Fix this anyway to make the warning disappear.
Long way: filter out "ND" , convert to numeric, then make the check.
