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 'NA's.

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))
