Working with FactoMineR
This will happen if you select no points when it asks you to 'click on the graph' (to select the level at which to cut the tree). On Windows you can select no points by right clicking and selecting 'Stop' from the menu that pops up. RStudio may have a different way to select no points. -Bill On Thu, Feb 4, 2021 at 9:04 AM Mahmood Naderan-Tahan

Hi,
I tried to run the HCPC example [1] in the online R [2], but got an error:
library(FactoMineR)
data(tea)
res.mca = MCA(tea, ncp=20, quanti.sup=19, quali.sup=c(20:36), graph=FALSE)
res.hcpc = HCPC(res.mca)
Result:
[1] "Click on the graph to cut the tree"
Error in while (coupe$y < min(t$tree$height)) { :
argument is of length zero
Calls: HCPC
Execution halted

May I know how to fix that?
