hi, hi all,

yes :)

# here are two propositions:

# first solution
scatter.dudi(dat.acm,clab.row=0)

# second solution
s.arrow(dat.acm$c1, xax=1, yax=2)
s.label(dat.acm$li, xax=1, yax=2, clabel=0,cpoint=1.5, add.p=T)
add.scatter.eig(dat.acm$eig, dat.acm$nf, xax=1, yax=2, posi = "top", ratio =
1/4)


regrads,
