Prints the results from a test of the difference between survival
curves using the output from surv.diff.
This function is deprecated.
USAGE:
print.surv.diff(x, digits=4)
REQUIRED ARGUMENTS:
x:
output list from the surv.diff function. Generally, an object of
class "surv.diff".
OPTIONAL ARGUMENTS:
digits:
number of significant digits to use in the printout.
SIDE EFFECTS:
A table is printed with columns giving the group label, the (weighted)
number of events observed, the expected number of events, and (O-E)^2/E.
The sum of the latter is an approximation to the chi-square statistic.
The actual chi-square statistic is also printed along with its p-value.
DETAILS:
Prints the results of the tests of the difference between two or more
survival curves using the G-rho family of tests. The test is performed
by the function surv.diff.
cancer.sdf <- surv.diff(cancer$time, cancer$status, cancer$inst, rho=.5)
print.surv.diff(cancer.sdf)
cancer.sdf # This will automatically print the nice table
print(cancer.sdf) # This will too.
