Survcomp {surv2sample} | R Documentation |
Create an object representing right-censored data with competing risks (types of failure).
Survcomp(time, event) is.Survcomp(x)
time |
survival times (possibly right-censored). |
event |
the status indicator, 0 = censored, 1 = dead from cause 1, 2 = dead from cause 2,... Successive integers 1,2,... must be used for causes. |
x |
any object. |
This is an extension of the standard function Surv
of
the package survival. Surv
allows only death and
censoring, while Survcomp
handles causes of death.
Survcomp
returns a matrix of class "Survcomp"
with two
columns (survival times,
event types) with attribute "ncauses"
containing the number
of different causes of death (which is max(event)
). There is a
print method for objects of class "Survcomp"
, and the function
is.Survcomp
for testing whether an object is of this class.
