Hello dear R help group.
I encountered this old thread (http://tinyurl.com/dklgsk) containing the a
similar question to the one I have, but left without an answer.
I am and hoping one of you might help.
A simplified situation: I have a factorial design (with 2^3 experiment
combinations), for 167 subjects, each one has answered the same question
twice (out of a bunch of "types" of questions).
Each answer could get an integer number between 0 to 3.
I wish to combine the two answers, but first to be sure I could, I would
have liked to run an ICC (Intraclass correlation) check on the two answers.
Naturally, I would use the irr, condord, or psy packages (as John Fox
suggested back then), but I can't because of the repetitions of different
design question for each patient.
Since the mentioned packages (irr, condord, and psy) Can take only a n*m
matrix for subjects and raters. But no place is given for the repetitions as
data and therefore it will be impossible to get results
for the INTRArater reliability.
Thanks,
Tal
