[R] Labels on a pyramide

[Orvalho Augusto]

I am using pyramid.plot() from the plotrix package.

I have something like this

############################################
xy.pop<-dados$masfr
xx.pop<-dados$femfr
#agelabels<-dados$femlab
xycol<-color.gradient(c(0,0,0.5,1),c(0,0,0.5,1),c(1,1,0.5,1),11)
xxcol<-color.gradient(c(1,1,0.5,1),c(0.5,0.5,0.5,1),c(0.5,0.5,0.5,1),11)
xylab<-dados$maslab
xxlab<-dados$femlab
agelabels<-xylab

png("piramide9808.png")
par(mar=pyramid.plot(xy.pop,xx.pop,labels=agelabels,top.labels=c("Masculino","","Feminino"),
       main="Primeiras 10 cancros mais frequentes por
sexo...",xycol=xycol,xxcol=xxcol,gap=0, labelcex=0))

dev.off()

The problem is (1) I do not want plot agelabels on the center and (2)
I want plot different labels for each pair of the bars (one label for
masculine and the other feminine).

The data represent the 10 most frequent cancer in a group of individuals.

Can some one help please?
