Wrapper over the predict function

This function is just a wrapper over the predict function. It sets different default parameters for models from different classes. For example: for classification random Forest is forces the output to be probabilities not classes itself.

yhat(X.model, newdata, ...)

# S3 method for lm
yhat(X.model, newdata, ...)

# S3 method for svm
yhat(X.model, newdata, ...)

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

# S3 method for ranger
yhat(X.model, newdata, ...)

# S3 method for default
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

Value

An numeric matrix of predictions. Can have more than one collumn.

Details

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