Warnmeldungen:
1: In if (x$datamean) { :
  Bedingung hat Länge > 1 und nur das erste Element wird benutzt (Condition
has length > 1 and only the first element is used) # It's normal? Why?
2: In if (x$datamean) { :
  Bedingung hat Länge > 1 und nur das erste Element wird benutzt
3: In if (x$datamean) { :

These are warnings and I think that you can safely ignore them.
It looks like the code should replace the line

  if (x$datamean)

with something like

  if (!is.null(x$datamean))
