Value
Description
This function return the X matrix for a fit possibly based on a different data frame than the model.
It performs a function very close to that of model.matrix except that model.matrix
expects the variable for the LHS of the formula to be in the data set, ostensibly in order to remove rows
for which the LHS variable(s) are NA. In addition, getX attaches the argument data set as an attribute.
Usage
1
Arguments
fit
a fitted object with formula method
data
(default NULL) a data frame on which to evaluate the design matrix
Details
Extending getX to new classes merely requires a getData method. The formula
method is also used but usually already exitsts.
Value
a design matrix
