\arguments{
\item{m}{Numerical value for the distribution mean.}

\item{s}{Numerical value for the distribution standard deviation.}

\item{L}{Numerical value representing the cutoff for a shaded lower tail.}

\item{U}{Numerical value representing the cutoff for a shaded upper tail.}

\item{M}{Numerical value representing the cutoff for a shaded central
region.}

\item{df}{Numerical value describing the degrees of freedom.  Default is
\code{1000}, which results in a nearly normal distribution. Small values may
be useful to emphasize small tails.}

\item{curveColor}{The color for the distribution curve.}

\item{border}{The color for the border of the shaded area.}

\item{col}{The color for filling the shaded area.}

\item{xlim}{Limits for the x axis.}

\item{ylim}{Limits for the y axis.}

\item{xlab}{A title for the x axis.}

\item{ylab}{A title for the y axis.}

\item{digits}{The maximum number of digits past the decimal to use in axes
values.}

\item{axes}{A numeric value denoting whether to draw both axes (\code{3}),
only the vertical axes (\code{2}), only the horizontal axes (\code{1}, the
default), or no axes (\code{0}).}

\item{detail}{A number describing the number of points to use in drawing the
normal curve. Smaller values correspond to a less smooth curve but reduced
memory usage in the final file.}

\item{xLab}{If \code{"number"}, then the axis is drawn at the mean, and
every standard deviation out until the third standard deviation. If
\code{"symbol"}, then Greek letters are used for standard deviations from
three standard deviations from the mean.}

\item{cex.axis}{Numerical value controlling the size of the axis labels.}

\item{xAxisIncr}{A number describing how often axis labels are placed,
scaled by standard deviations. This argument is ignored if \code{xLab =
"symbol"}.}

\item{add}{Boolean indicating whether to add this normal curve to the
existing plot.}

\item{\dots}{Additional arguments to \code{plot}.}
