Print Method for rmst_fast Objects

Formats and prints an rmst_fast object. In single-group mode it shows the restricted mean survival time, its Greenwood standard error, and the Wald confidence interval at the requested horizon. In two-group mode it shows the per-group restricted mean survival times together with the difference (treatment minus control) and ratio (treatment over control) contrasts, each with a Wald z-statistic and two-sided p-value.

Usage

# S3 method for class 'rmst_fast'
print(x, digits = max(1L, getOption("digits") - 3L), ...)

Arguments

x

An object of class "rmst_fast" returned by rmst_fast.

digits

Number of significant digits to display. Defaults to the global option getOption("digits").

...

Additional arguments (currently unused).

Value

Invisibly returns x.
