predict.mca {MASS}

R Documentation

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.
