Hi! Have the following factors with the following levels. tmp$norm [1] rank rank rank rank rank log log log rank sqrt sqrt sqrt log log rank [16] rank rank sqrt sqrt sqrt sqrt log log log log sqrt none none none none [31] none none none none sqrt none Levels: log none rank sqrt
I would like to add an ordering to the levels. none<sqrt<log<rank I tried with tmp$norm <-factor(tmp$norm,labels = c("none","sqrt","log","rank"),ordered=T) >tmp$norm [1] log log log log log none none none log rank rank rank none none log [16] log log rank rank rank rank none none none none rank sqrt sqrt sqrt sqrt [31] sqrt sqrt sqrt sqrt rank sqrt Levels: none < sqrt < log < rank But this is not what I would like to have because the command not only superimposes an ordering but also changes the factors!
