By coincidence, there actually _is_ enough info to pinpoint the issue:
*Subj Group Emotion Response*94 HR Happy 2 119 HC Happy 0 .... 3 HR Sad 4 61 HC Sad 2 64 HC Sad 0 ....etc An unreplicated complete block design has exactly 1 observation for each combination of the two grouping factors. The above clearly has 2 observations with "HC, Sad". So Friedman's test does not apply. > On 13 Apr 2015, at 18:27 , John Kane <jrkrid...@inbox.com> wrote: > > We really need " commented, minimal, self-contained, reproducible code' as > asked for in the note at the end of each R-help message. > > Have a look at http://adv-r.had.co.nz/Reproducibility.html and/or > http://stackoverflow.com/questions/5963269/how-to-make-a-great-r-reproducible-example > for some hints. > > In particular, in your case we almost certainly need some data.
