To calculate this with the kappam.fleiss-function of irr, I need a data.frame like this: (id of 1st voter) (id of 2nd voter) party spd cdu Of course I don't plan to calculate this with the million of cases mentioned in the table above (I am working on a small laptop).

Hi All, I am using fleiss kappa for inter rater agreement. Are there any know issues with Fleiss kappa calculation in R? Even when I supply mock data with total agreement among the raters I do not get a kappa value of 1. instead I am getting negative values. I am using the irr package version 0.70 Any help is much appreciated. Thanks and Regards M [[alternative HTML version deleted]]

...alize differences between malignant and benign more than differences between malignant and probably malignant. I only found the weighted option in the 2-rater functions (kappa2, wkappa, cohen.kappa). The functions I found for multiple raters do not include a weighted option for categorical data (kappam.fleiss, kappam.light, lkappa). Anyone know a function that allows the calculation of weighted kappa for m raters? Thanks in advance! ~Marwa [[alternative HTML version deleted]]

...n I try to use the boot.sw98 to come up with some sensitivity analysis I get the following error: boot.sw98(XOBS=x,YOBS=y,NREP=100,DHAT=dhat,RTS=3,ORIENTATION=2) Error in 0:L : NA/NaN argument In addition: Warning message: longer object length is not a multiple of shorter object length in: kappam * Gcounts What does this mean? Is this because I have too many observations? What can I do to fix it? Please let me know if you need further information. Thank you in advance for your cooperation.

Hi, I have two separate questions relating to the KernSmooth package. I am using the dpik function from the KernSmooth package and receive the error Warning message: In kappam * Gcounts : longer object length is not a multiple of shorter object length I saw an earlier post , but the issue was using the bkde fxn and the person appeared to be using too small of a bandwidth. However, dpik returns a bandwidth and therefore I am not sure why I am getting this error....

...ot;number of medical doctor" and "number of video") in a row. In addition there is a medical doctor number 21 who is assumed to be a gold-standard. As measure of inter-observer-agreement I calculated kappa according to Fleiss and simple agreement in percent using the routines "kappam.fleiss" and "agree" from the irr-package. Everything worked fine so far. Now I'd like to calculate specificity, sensitivity and accuracy for each item (compared to the gold-standard), as these are well-known and easy to understand quantities for medical doctors. Unfortunately I...

Dear R-colleagues, another question from a newbie: I am creating a lot of simple pivot-charts from my raw data using the reshape-package. In these charts we have medical doctors judging videos in the columns and the videos they judge in the rows. Simple example of chart/data.frame "input" with two categories 1/0: video 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 1 1 0 0
