R help - Sep 2012 - boxplot names italic

Hello

I have two boxplots and want the names to be in italic, which works fine, except
that the second name (Sinapis) is raised, compared to the first name:

bicran<-c(0.55,0.25,0.6,0.83,0.11,0,0.67,1.36,0.9,1.09)
bicsin<-c(0.09,0.53,0.45,0.38,1.18,0.45,0.78,1.17,1.22,1.4)
ran.text<-expression(italic(Ranunculus))
sin.text<-expression(italic(Sinapis))
boxplot(bicran, bicsin, names=c(ran.text, sin.text))
mtext("(N=10)", side=1,line=1, adj=0.43,cex=0.9)
mtext("(N=10)",side=1,line=1,adj=0.9, cex=0.9)


Is there anything I can do against that? With the names in regular letters there
is no problem, the names show up on the same level:

boxplot(bicran, bicsin, names=c("Ranunculus", "Sinapis"))

Thanks and cheers, Sarah

Hi Sarah,
Try this:

boxplot(bicran, bicsin, names=c("",""))
mtext(c(ran.text,sin.text),at=1:2,line=c(0.9,1),side=1)

That looks about right, but you can fiddle with it.
