Hi - I'm trying to run Krippendorff's alpha for data consisting of 4 subjects rated on 6 events each by three raters. The ratings are interval ratio scale data.
I've rearranged my data into a 3 x 24 of ratersXevents. (per this discussion on CrossValidated: ( https://stats.stackexchange.com/questions/255164/inter-rater-reliability-for-binomial-repeated-ratings-from-two-or-more-raters/256144#256144) ). This is the code I've used: library(irr) dat <- read.csv(file.choose(), header = TRUE) head(dat) kripp.alpha(dat, method=c("ratio")) #### error message: Error in sort.list(y) : 'x' must be atomic for 'sort.list' Have you called 'sort' on a list? kripp.alpha(dat,"ratio") #### error message: Error in sort.list(y) : 'x' must be atomic for 'sort.list' Have you called 'sort' on a list? I read rhelp on sort, but I'm still confused. Please help! Thank you! PS I arranged my data in that matrix based upon this comment and response from the CrossValidated posting forum ( https://stats.stackexchange.com/questions/255164/inter-rater-reliability-for-binomial-repeated-ratings-from-two-or-more-raters/256144#256144), but my question above was rejected there.
