What does “argument to 'which' is not logical” mean in FactoMineR MCA?

Question

I\'m trying to run an MCA on a datatable using FactoMineR. It contains only 0/1 numerical columns, and its size is 200.000 * 20.

require(FactoMineR)
result &         


        

Answer 1

Same problem as well and changing to factor did not solve my answer either, because I had put every variable as supplementary.

What I did first was transform all my numeric data to factor :

Xfac = factor(X[,1], ordered = TRUE)
for (i in 2:29){
  tfac = factor(X[,i], ordered = TRUE)
  Xfac = data.frame(Xfac, tfac)
}
colnames(Xfac)=labels(X[1,])

Still, it would not work. But my 2nd problem was that I included EVERY factor as supplementary variable ! So these :

MCA(Xfac, quanti.sup = c(1:29), graph=TRUE)
MCA(Xfac, quali.sup = c(1:29), graph=TRUE)

Would generate the same error, but this one works :

MCA(Xfac, graph=TRUE)

Not transforming the data to factors also generated the problem.
