I am Using R.2.9.2 and I am trying to make nicer some graphics, which  
are constructed with plotmer.fnc. In particular, I have two questions:

1. Is is a way to decide in which order we want the labels on the  
x-axis. For now, the reference value label is the first one, and the  
other labels appear in the alphabetical order. I would like them to be  
sorted in the ascending way. Here is my code:

plotLMER.fnc(idtt_lmer7bis, xlabel ="", xlabs =NA, ylabel = "Reaction  
time (ms)", fun = NA, pred = "Condition", n = 100, , mcmcMat = NA,  
lockYlim = TRUE, addlines = TRUE, withList = FALSE, cexsize = 0.7,  
lwd=2, font=2, cex.lab=1.25, tcl=-0.5, las=2, cex.axis=0.7)

2. In the plotlmer graphic with an interaction, is it possible to  
remove the legend of the interacted factor? Again here is my code:

plotLMER.fnc(idbase_lmer22bis, xlabel = "Competence in L2", xlabs =  
NA, ylabel = "Reaction time (ms)", ylimit =c(300,1300), fun = NA, pred  
= "Groupe", n = 100, intr=list("Lexical_status", c("Word",  
"PseudoWord"), "end", list(c("red",  "blue"), lty=c(1,4), rep(1,2))),  
mcmcMat = NA, lockYlim = TRUE, addlines = TRUE, withList = FALSE,  
cexsize = 1, lwd=2, font=2, cex.lab=1.25, tcl=-0.5).

Sorry if these questions are trivial, but I am been looking for an  
answer for two entire days now, and I would really appreciate your
