Jason, It seems that your version of psych may be outdated. CRAN currently has version 1.0-88, in which wkappa is listed as deprecated. Might be time to upgrade.

Thanks for you quick responses, all! Bill, it looks like that's just what I want, but I'm not sure where you're getting the cohen.kappa() function. The only function I could find by that name is in the concord library, and it gives me:x<-c("red", "yellow", "blue", "red") #coder number 1 y<-c("red", "blue", "blue", "red") #coder number 2 ck<- cohen.kappa(cbind(x,y))Error in counts[i, j]<- sum(scores[i, ] == score.levels[j], na.rm = TRUE) : subscript out of bounds In addition: Warning messages: 1: NAs introduced by coercion 2: NAs introduced by coercion wkappa in the psych lib gives me Error in tr(x) : m must be a square matrix
