Hi,
The label you want to see on the factorial map should be the row names
so change first the row names and then do your analysis using
FactoMineR. Then apply the code hereunder replacing res by your PCA object.
plot.PCA(res, axes=c(1, 2), choix="ind", habillage="ind",
col.ind="black", col.ind.sup="blue",
col.quali="magenta", label=c("ind",
"ind.sup", "quali"), title="")

parameter but i could only manage to label the supplementary individuals with
there "row.names" (i.e. label="indiv.sup") and not with the
specific names i would like them to display (gathered in a data-frame column for
example, characters or numeric...).
