[R] ordering a factor in boxplot output

[S Ellison]

The factor order defaults to alphabetical, and boxplot follows that.
Re-ordering the factor to the order of interest is probably the best way
of handling it. 

However, if you don;t want to do that, you could perhaps also use the
at= parameter in boxplot. For example

x<-rnorm(50)
g<-factor(rep(c("B","A"),each=25))

boxplot(x~g)

boxplot(x~g, at=c(2,1))

I'm sure I'm missing something obvious in the documentation...

I'm generating a boxplot 
boxplot(CleanValue~ApptCategory*ReportingCode,data=newfile)
where ApptCategory is a factor with possible values
("New","Established")

Problem is, the output orders those factors alphabetically, and I'd
really
rather see New come first. I'm apparently confused by the "reorder"
function
because somehow my attempts to apply it have resulted in reversing the
labelling (so now the established boxes are labelled as new).

What am I missing?  Thanks.
