| \description{ |
| Printing objects of class \code{"htest"} or \code{"power.htest"}, |
| respectively, by simple \code{\link{print}} methods. |
| } |
| \usage{ |
| \method{print}{htest}(x, digits = getOption("digits"), prefix = "\t", \dots) |
| |
| \method{print}{power.htest}(x, digits = getOption("digits"), \dots) |
| } |
| \arguments{ |
| \item{x}{object of class \code{"htest"} or \code{"power.htest"}.} |
| \item{digits}{number of significant digits to be used.} |
| \item{prefix}{string, passed to \code{\link{strwrap}} for displaying |
| the \code{method} component of the \code{htest} object.} |
| \item{\dots}{further arguments to be passed to or from methods.} |
| } |
| \details{ |
| Both \code{\link{print}} methods traditionally have not obeyed the |
| \code{digits} argument properly. They now do, the \code{htest} |
| method mostly in expressions like \code{max(1, digits - 2)}. |
| |
| A \code{power.htest} object is just a named list of numbers and |
| character strings, supplemented with \code{method} and \code{note} |
| elements. The \code{method} is displayed as a title, the \code{note} |
| as a footnote, and the remaining elements are given in an aligned |
| \sQuote{name = value} format. |
| } |
| \value{ |
| the argument \code{x}, invisibly, as for all \code{\link{print}} |
| methods. |
