Used to compute coordinates for additional rows or additional factors in a multiple correspondence analysis.
# S3 method for mca
predict(object, newdata, type = c("row", "factor"), …)An object of class "mca", usually the result of a call to mca.
A data frame containing either additional rows of the factors used to
fit object or additional factors for the cases used in the
original fit.
Are predictions required for further rows or for new factors?
Additional arguments from predict: unused.
If type = "row", the coordinates for the additional rows.
If type = "factor", the coordinates of the column vertices for the
levels of the new factors.
