boxplot with text and symbols on x

Hello R-user community!

I am running R 2.7.0 on a Power Book (Tiger). (I am still R and statistics
beginner)

I did the following :

pdf("InLnegthMaxHomogeneity.pdf")
boxplot(inflorescence_length_Max~Sex, main="Bartletts Homogeneity for
inflorescence length",data=FemMal_Sex)
Homo<-bartlett.test(FemMal_Sex$inflorescence_length_Max,FemMal_Sex$Sex)
text( 2, 500, "Bartlett's K-squared=", col='red',adj = c(1,0) )
text( 2, 500, round(Homo$statistic,digits=5), col='red' ,adj = c(0,0))
text( 2, 480, "df=", col='red',adj = c(1,0) )
text( 2, 480, Homo$parameter, col='red' ,adj = c(0,0))

text( 2, 460, "p-value=", col='red', adj = c(1,0))
text( 2, 460, round(Homo$p.value,digits=5), col='red', adj = c(0,0))

dev.off()


As I am still not very good in R, I guess it is not the  easiest way to
implement the text and it was kind of fiddling around to find the right
position for the text.
I would be glad if somebody would have an easier solution.

My second question is about adding symbols (usual male and female symbol) to
the x-axis to label the boxes.

I would be very glad if somebody could help mw with this.

Many thanks in advance.
