predict.mca

From MASS v7.3-35 by Brian Ripley

Used to compute coordinates for additional rows or additional factors in a multiple correspondence analysis.

## S3 method for class 'mca':
predict(object, newdata, type = c("row", "factor"), ...)

object: An object of class "mca", usually the result of a call to mca.
newdata: 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.
type: 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.
