## S3 method for class 'randomForest'
yhat(X.model, newdata, ...)

## Default S3 method:
yhat(X.model, newdata, ...)

Arguments

X.model

object - a model to be explained

newdata

data.frame or matrix - observations for prediction

...

other parameters that will be passed to the 'predict' function

Details

We use the 'yhat' name instead of 'predict' since we need different defaults that the one set in the 'predict' function.
