Stores one or more survival stepfunctions of the Kaplan-Meier and Breslow type.
Object of class "vector". The time points at which the function starts, jumps or ends.
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).
(breslow): Coerces the object to a matrix (as as.matrix) and selects rows and/or columns.
(breslow): Selects a subset of the curves.
(breslow): Returns the "curves" slot together with the "time" slot in a
(breslow): Coerces the object to a list.
(breslow): Returns the "curves" slot with the "time" slot as column names.
(breslow): Straightforward plotting (all curves in one plot).
(breslow): Summarizes the dimensions of the object.
(breslow): Takes a second argument (
time). Extracts the value of the survival curve(s) at any time point.
Breslow objects are generally created by the
penalized function and related functions.
