Print Methods for Hypothesis Tests and Power Calculation Objects

Description

Printing objects of class "htest" or "power.htest", respectively, by simple print methods.

Usage

## S3 method for class 'htest'
print(x, digits = getOption("digits"), prefix = "\t", ...)

## S3 method for class 'power.htest'
print(x, digits = getOption("digits"), ...)

Arguments

Details

Both print methods traditionally have not obeyed the digits argument properly. They now do, the htest method mostly in expressions like max(1, digits - 2).

A power.htest object is just a named list of numbers and character strings, supplemented with method and note elements. The method is displayed as a title, the note as a footnote, and the remaining elements are given in an aligned ‘name = value’ format.

Value

the argument x, invisibly, as for all print methods.

Examples

(ptt <- power.t.test(n = 20, delta = 1))
print(ptt, digits =  4) # using less digits than default
print(ptt, digits = 12) # using more  "       "     "
