You _think_ ??? Documentation, please... The boxplots certainly move if I do plot(result ~ type, tmp) plot(result ~ factor(type, levels=c("c","b","a")), tmp) > of the boxplot did not. So there is some problem there. I also tried > as.factor(tmp$type); levels(tmp$type)=c("c", "b", "a") and got the same That changes the level _names_: 1st group name becomes "c" instead of "a"; you want the 3rd group to become the 1st but still be called "c". -pd > thing. > Thanks. > Li > > 2015-09-14 21:44 GMT-04:00 Jeff Newmiller <jdnew...@dcn.davis.ca.us>: > >> Make your factor variable deliberately.
