Dear all,

in the attached file, there are many NAs that I treat with imputeMCA:

tab.disj.comp <- imputeMCA(df, ncp = 1) (if someone can tell me why ncp should be 1 that would be great)

If I then use MCA:

mca1 <- MCA(df, tab.disj = tab.disj.comp, graph = TRUE)

I get a really general error message: Error in 1:nrow(X) : argument of length 0

Does anyone know what this means?

Many thanks,

Annemarie

Hi,
You need to use the tab.disj object:

tab.disj.comp <- imputeMCA(df, ncp = 1)

mca1 <- MCA(df, tab.disj = tab.disj.comp$tab.disj, graph = TRUE)
