model.frame.ddformula: model.frame and model.matrix for ddformula

Description

Functions added to handle fixed (time-invariant) intercept coefficient for ddhazard. model.frame.ddformula always has drop.unused.levels = FALSE regardless of the input.

Usage

# S3 method for ddformula
model.frame(formula, data = NULL, subset = NULL,
  na.action = na.fail, xlev = NULL, ...)
# S3 method for ddformula
model.matrix(object, data = environment(object),
  contrasts.arg = NULL, xlev = NULL, ...)
