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="")

Dear all,
i'm trying to label specific individuals (supplementary ones) after a PCA with the FactoMiner package. There
is not much details (possibilities?) in the R-help of the plot.pca function. There is indeed a
"label" 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...).
I saw that i might resolve my problem with the ade4 package (s.plot function or
something like that) but i would like to stick to factominer, if there is a way
to manage this label issue... Did anyone deal with that before ?
Thanks for your help,
with regards.
