R: Coeffients from CoxBoost fit

coef.CoxBoost {CoxBoost} | R Documentation

## Coeffients from CoxBoost fit

### Description

Extracts the coefficients from the specified boosting steps of a CoxBoost object fitted by `CoxBoost`.

### Usage

    ## S3 method for class 'CoxBoost'
    coef(object,at.step=NULL,scaled=TRUE,...)

### Arguments

`object` | fitted CoxBoost object from a `CoxBoost` call.
`at.step` | scalar or vector of boosting step(s) at which prediction is wanted. If no step is given, the final boosting step is used.
`scaled` | 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.

### Value

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).
