Print Method for medsurv_fast Objects

Source: R/print.medsurv_fast.R
print.medsurv_fast.Rd

Formats and prints a medsurv_fast object in the same layout as the other two-group estimation summaries in the package. The header shows the control label and the inference settings. The body shows the per-group median survival with its confidence interval, followed, for a two-group object, by the difference contrast (treatment minus control) with a confidence interval, the test statistic, and the p-value. The p-value column is labeled Pr(>|z|) for a two-sided test and Pr(>z) for a one-sided test, whose p-value is the upper tail in the direction of treatment benefit.

Usage

# S3 method for class 'medsurv_fast'

Arguments

An object of class "medsurv_fast" returned by medsurv_fast.

digits

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

...

Additional arguments (currently unused).

Value

Invisibly returns x.
