[R] randomizing groups

I have a list of participants in a study, identified by number. I want to randomly sort them into an arbitrary number of groups. split(sample(1:96, 96), 1:16) almost does it, but it only works where the division is even. Any ideas? Thanks! Jason Priem, Doctoral Student, School of Information

[R] [Fwd: Re: randomizing groups]

Duh. I just figured out that though I was getting a warning, it was still doing the split anyway. Sorry for the dumb question. -jason Jason Priem wrote: I have a list of participants in a study, identified by number. I want to randomly sort them into an arbitrary number of groups. split

[R] Cohen's Kappa for beginners

Kappa using the wkappa function in the psych package. The only example in the docs is using a matrix, which I'm afraid I don't understand--I don't know how to get there from what I've got. Could anyone point me in the right direction? Thanks! Best, Jason -- J

Re: [R] Cohen's Kappa for beginners

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<-
