[R] boxplot with text and symbols on x

[Birgit Lemcke]

Thanks that was a huge help.

Now I am using this:

pdf("InfLengMaxVarHomogeneity.pdf")
plot(inflorescence_length_Max~Sex,xaxt="n"  #unterdrückt "normale x- 
Achse
, ylab="inflorescence length max", main="Bartletts Homogeneity for  
inflorescence length Max",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))
axis(1,at=c(1,2) #Mache punkte auf Achse in Position 1 und 2
, lab=expression( "\u2642", "\u2640")) #zeichne dort Mann/Frau Symbole
dev.off()


But the symbols do not appear in the pdf. What is the reason for that  
and how can I create a pdf with the symbols.

Thanks again

Birgit
