Extracts the coefficients from the specified boosting steps of a CoxBoost
object fitted by CoxBoost.
# S3 method for CoxBoost
coef(object, at.step = NULL, scaled = TRUE, ...)For a vector of length p (number of covariates)
(at.step being a scalar) or a length(at.step) * p matrix
(at.step being a vector).
fitted CoxBoost object from a CoxBoost call.
scalar or vector of boosting step(s) at which prediction is wanted. If no step is given, the final boosting step is used.
logical value indicating whether coefficients should be
returned scaled to be at the level of the original covariate values, or
unscaled as used internally when standardize=TRUE is used in the
CoxBoost call.
miscellaneous arguments, none of which is used at the moment.
