Daer John,
Thanks! My problem is that in the mentioned packages (irr, condord, and psy)
only a n*m matrix for subjects and raters can be given as data. So I can not
give the repetitions as data and therefore it will be impossible to get results
for the INTRArater reliability.
Regards,
Karl

Dear Andrew and Karl,
See the irr, condord, and psy packages.
