Format P Values

Description

format.pval is intended for formatting p-values.

Usage

format.pval(pv, digits = max(1, getOption("digits") - 2),
            eps = .Machine$double.eps, na.form = "NA")

Arguments

pv

a numeric vector.

digits

how many significant digits are to be used.

eps

a numerical tolerance: see ‘Details’.

na.form

character representation of NAs.

Details

format.pval is mainly an auxiliary function for print.summary.lm etc., and does separate formatting for fixed, floating point and very small values; those less than eps are formatted as "< [eps]" (where ‘[eps]’ stands for format(eps, digits)).

Value

A character vector.

Examples

format.pval(c(stats::runif(5), pi^-100, NA))
format.pval(c(0.1, 0.0001, 1e-27))
