Hi, I created a simple data frame with one factor and one numerical variable. The factor was actually a vector of names of techniques to trimm reaction time data. I want to create a plot that shows the value of F test for every trimming method. So the data frame has its trim factor (who has those labels "mean","2500","2000","1500","1000","log","inverse","1SD","2SD") and the numerical variable of the data frame has the F values for each one of those trimming method. When I ask R to plot it, it doesn''t keep the order of the trimm verctor correctly and the plot confuses the order so the most left one will be 1500 and then 1SD etc. The values are correct but it is important for me to keep it in the same order I built it. How can I do it? Thank you very much, Or D. [[alternative HTML version deleted]]
Hi Or, I can't know for sure what your problem is without an example, but the first thing I would do is check to make sure that your labels are stored as an ordered factor (and that the order is correct). See ?factor for details.

Ok, It seems that the problem lays in the order (as Ista mentioned), But, when I ask R to order it he chooses to order it by size and not by the specific order I mentioned when I built the vector. Is it possible to tell him to keep the order as mentioned? Thank you.
