Test the survival difference between groups of patients
Description
Test the survival difference between groups of patients
Usage
testSurvival(survTerms, ...)
Arguments
survTerms |
survTerms object: survival terms obtained after
running processSurvTerms (see examples)
|
... |
Arguments passed on to survival::survdiff
- subset
-
expression indicating which subset of the rows of data should be used in
the fit. This can be a logical vector (which is replicated to have
length equal to the number of observations), a numeric vector indicating
which observation numbers are to be included (or excluded if negative),
or a character vector of row names to be included. All observations are
included by default.
- na.action
-
a missing-data filter function. This is applied to the model.frame after any
subset argument has been used. Default is options()$na.action .
- rho
-
a scalar parameter that controls the type of test.
- timefix
process times through the aeqSurv function to
eliminate potential roundoff issues.

Value
p-value of the survival difference or NA
Note
Instead of raising errors, an NA
is returned
Examples
require("survival")
data <- aml
timeStart <- "event"
event <- "event"
followup <- "time"
data$event <- NA
data$event[aml$status == 1] <- aml$time[aml$status == 1]
censoring <- "right"
formulaStr <- "x"
survTerms <- processSurvTerms(data, censoring=censoring, event=event,
timeStart=timeStart, followup=followup,
formulaStr=formulaStr)
