[R] Correspondence analysis with R -follow up

[Emanuele Mazzola]

Hi all,

thank you for your answers; i've tried both cca from vegan library, and 
dudi.coa from ade4 library; one last question: my deal is mainly with 
contingency tables, like the one i'm posting here

acciaieria<-c(.41,.02,.44,.04,.09)
laminatoio<-c(.34,.28,.26,.01,.11)
fonderia<-c(.48,.05,.34,.08,.05)
leghe<-c(.45,.19,.25,.03,.08)
pct<-cbind(acciaieria,laminatoio,fonderia,leghe)
pct<-data.frame(pct,row.names=c("normale","preparaz.","manutenz.","installaz.","trasferim."))

BUT...cca and dudi.coa seem to return quite different graphical results; 
where am i doing wrong?
Do they do the same to you with the table above?

Thank you very much again!
Bye
Emanuele
