Hi Halllie, As Jeff noted, a data frame is not a matrix (it is a variety of list), so that looks like your problem.
hkdf<-data.frame(sample(3:5,4,TRUE),sample(1:3,4,TRUE),sample(2:4,4,TRUE), sample(3:5,4,TRUE),sample(1:3,4,TRUE),sample(2:4,4,TRUE)) library(irr) kripp.alpha(hkdf) kripp.alpha(as.matrix(hkdf)) Jim On Mon, Jan 28, 2019 at 6:04 PM Hallie Kamesch <hallie.kame...@gmail.com> wrote: > > Hi - > I'm trying to run Krippendorff's alpha for data consisting of 4 subjects > rated on 6 events each by three raters.
