breslow object {penalized} | R Documentation |
Breslow estimator object
Description
Stores one or more survival stepfunctions of the Kaplan-Meier and Breslow type.
Details
Breslow objects are generally created by the penalized
function and related functions.
Slots
time
:- Object of class "vector". The time points at which the function starts, jumps or ends.
curves
:- Object of class "matrix". The values of the curve at each time point.
Note that the function is left-continuous. Curves are stored as a matrix of dimension (# curves) x (# timepoints).
Methods
- "["
- (breslow): Coerces the object to a matrix (as as.matrix) and selects rows and/or columns.
- "[["
- (breslow): Selects a subset of the curves.
- as.data.frame
- (breslow): Returns the "curves" slot together with the "time" slot in a
data.frame
.
- as.list
- (breslow): Coerces the object to a list.
- as.matrix
- (breslow): Returns the "curves" slot with the "time" slot as column names.
- plot
- (breslow): Straightforward plotting (all curves in one plot).
- show
- (breslow): Summarizes the dimensions of the object.
- survival
- (breslow): Takes a second argument (
time
). Extracts the value of the survival curve(s) at any time point.
