\title{gsplot date axis}

\usage{

date_axis(object, ...)

date_axis.gsplot(object, ..., side, pos.lab = "tick", at = NULL,

tick.int = NULL, snap.to = "day")

date_axis.default(side, pos.lab = "tick", tick.int = NULL, snap.to = NULL,

...)

}

\arguments{

\item{object}{gsplot object}

\item{\dots}{Further graphical parameters may also be supplied as arguments. See 'Details'.}

\item{side}{side to place the axis on}

\item{pos.lab}{where should the label be positioned, centered on the "tick" or "interval".}

\item{at}{specific location to place ticks}

\item{tick.int}{interval in which ticks should be placed, alternative to defining at.}

\item{snap.to}{set the limits to coincide with temporal boundaries. Accepts "day", "week", "month", "quarter",

"year", "wateryear", "decade".}

}

\description{

Special axis for date handling, including interval labelling.

Additional graphical parameter inputs:
