# X is a data.frame and contains NA
x <- taste[, 2:7]
x[1,1] <- NA

# X is a list of indicators and contains NA
x <- list(nif = indicator(taste[, 2:3]), hurma = indicator(taste[, 4:5]))
x[[1]][1,1] <- NA
what.is.x(x)

# X contains elements that are neither a matrix nor a data.frame
x <- list(nif = 1:10, taste[, 1:3], taste[, 4:7])
