Hello Members, I try to convert variables in a data.frame (bract.awn) in the class ordered.
str(bract.awn) 'data.frame': 348 obs. of 2 variables: $ bracts.length.relative.to.flower...............Min: Factor w/ 4 levels "1","2","3","4": 2 3 3 3 3 2 1 4 3 2 ... $ bract.awn.relative.to.body.................Max : Factor w/ 4 levels "1","2","3","4": 1 3 2 1 4 1 1 1 1 1 I tried this: bract.awn<-as.ordered(bract.awn) Fehler in sort.list(unique.default(x), na.last = TRUE) : 'x' must be atomic for 'sort.list' Have you called 'sort' on a list? What am I doing wrong? Thanks a lot in advance.
