I loved your code using FactoMineR, I have obtained amazing plots using huge databases… However, I encountered problems when having “0″ in any data matrix and the package MissMDA did not help… Any suggestions?

Some columns have “0″, some others are full of “0″, but I discarded those… Maybe MCA is better for categorical variables? I am trying with the correspondence analysis…

When you say “0″ do you mean missing values? Or does it mean that you have very sparse matrices? Or maybe columns full of “0″?
