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

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.

Answer 1

Are the classes of your variables character or factor?I was having this problem. My solution was to change al variables to factor.

#my data.frame was "aux.da"
i=0
while(i < ncol(aux.da)){
  i=i+1  aux.da[,i] = as.factor(aux.da[,i])
}
