R help - Mar 2013 - ggpliot2: reordering of factors in facets facet.grid(). Reordering of factor on x-axis no problem.

Hi everyone (again),
before you all start screaming that the reordering of factors has been 
discusse on several threads and is not particular to ggplot2, hear me out.
I can easily reorder my x-axis factor in facet.grid() in ggplot2. What I 
cannot reorder are the factors represented on the strips. I can see that the 
graphs are changing, so I am afraid of what it is I am doing. Why is ggplot2 
not changin the strip labels if indeed the factor-order has been changed? 
or have I missed to add code defining the factor-labels in the strips. I 
have not found such code as it has been done automatically from my dataframe 
using facet.grid() previously. I am simply afraid of displaying the wrong 
things without noticing it.
Here is my code and comments:

I want to have my factor 1 in the order: "F", "E",
"C", "D", "A", "B"
instead of alphabetical. My normal methods do not work.

with kind regards
Anna Zakrisson

# Some dummy data:
mydata<- data.frame(factor1 = factor(rep(LETTERS[1:6], each = 80)),
                    factor2 = factor(rep(c(1:5), each = 16)),
                    factor3 = factor(rep(c(1:4), each = 4)),
                    var1 = rnorm(120, mean = rep(c(0, 3, 5), each = 40),
                                 sd = rep(c(1, 2, 3), each = 20)),
                    var2 = rnorm(120, mean = rep(c(6, 7, 8), each = 40),

Your problem is simple. factor1 is a factor with the desired levels.
But you did not facet by factor1, you faceted by Grouping. You just
need to replace

  facet_wrap(~Grouping, ncol = 2)

with

  facet_wrap(~factor1, ncol = 2)

If I try  facet_wrap(~factor1, ncol = 2) I get no faceting at all. Strange.

Anna,
   You're right.  Something I am doing seems to be messing up RStudio every
   once in a while.  I rebooted it and the faceting is working just fine both
   with just the required packages loaded and with my normal set of packages.
   I had real trouble getting the legend.position command to work until I
   rebooted RStudio and now this.
   I have no idea of how to track  down what's happening but at least
you've
   made me aware of it.
   Thanks

   Reordering of factor on x-axis no problem.

   Dear John and Ista,

   Ista: Thank you so much for your help and for not shouting :-)
   Sometimes one goes blind having stared at a script for too long. I realize
   that the grouping is not needed at all - it is the remnant from another
   figure I made showing two factor 1 -levels per plot instead of just one
   level.

   John:   It   works   for   me.   You  mentioned  previously  that  the
   geometric.line(blabla dodge) didn't work because you had some other
packages
   open. Maybe that is the case again? If you find out what it is, please
   share! It is good to know which packages disturb each other!

   Once again, thank you so much! Another day closer to disputation... :-S

     Subject: Re: [R] ggpliot2: reordering of factors in facets facet.grid().
     Reordering of factor on x-axis no problem.

   If I try  facet_wrap(~factor1, ncol = 2) I get no faceting at all. Strange.
