print.power.htest: 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 htest
print(x, digits = getOption("digits"), prefix = "\t", …)
# S3 method for power.htest
print(x, digits = getOption("digits"), …)

Arguments

x

object of class "htest" or "power.htest".

digits

number of significant digits to be used.

prefix

string, passed to strwrap for displaying the method component of the htest object.

…

further arguments to be passed to or from methods.

Value

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

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.

Examples

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