Application of Models to New Data

In most cases, the function used to create a model (e.g. PCA, PLS, etc) is also used to make a prediction with the created model. See the function used for more information on this. In addition, these utilities may be of use for certain applications.

modelselector - Create or apply a model selector model.
compressmodel - Remove references to unused variables from a model.   [demo]
matchvars - Align variables of a dataset to allow prediction with a model.   [demo]
pcapro - Projects new data on old principal components model.   [demo]
