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$height)) { :
argument is of length zero
Calls: HCPC
Execution halted
[1] "Click on the graph to cut the tree"
Error in while (coupe$y < min(t$tree$height)) { :
argument is of length zero
Calls: HCPC
Execution halted
May I know how to fix that?

Hi, Could you send a sample of your data frame?

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 <mahmood.naderan at ugent.be> wrote:> > 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$height)) { : > argument is of length zero > Calls: HCPC > Execution halted > > > [1] "Click on the graph to cut the tree" > > Error in while (coupe$y < min(t$tree$height)) { : > > argument is of length zero > > Calls: HCPC > > Execution halted > > > > May I know how to fix that? > > > > [1] http://factominer.free.fr/factomethods/hierarchical-clustering-on-principal-components.html > > [2] https://rdrr.io/snippets/ > > > Regards, > Mahmood > > [[alternative HTML version deleted]] > > ______________________________________________ > R-help at r-project.org mailing list -- To UNSUBSCRIBE and more, see > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code.
