TITLE(oz @@ Plot the Australian coastline and states)
USAGE(
oz(states = TRUE, coast = TRUE, xlim = c(113, 154),
   ylim = c(-44, -10), add = FALSE, ar = 1, eps = 0.25,
   sections = 1:16, visible, ...)
)
ARGUMENTS(
ARG(states @@ logical flag: include mainland internal state boundaries?)
ARG(coast @@ logical flag: include coastline?)
ARG(xlim @@ optional limits for the x-axis (longitude).)
ARG(ylim @@ optional limits for the y-axis (latitude).  (N.B. all
latitudes for Australia are south, and hence are NEGATIVE.))
ARG(add @@ logical flag.  If TRUE, the plot is superimposed on an
existing plot.  Otherwise, a new plot is generated.)
ARG(ar @@ aspect ratio: longitude to latitude.)
ARG(eps @@ If LANG(sections) (q.v.) is specified explicitly, the plot is
enlarged four ways by this amount (degrees).)
ARG(sections @@ integer vector specifying which LANG(sections) of the
plot are to be included in the range calculation.  The sections are as
follows: 1-7, coastlines of WA(1), NT(2), QLD(3), NSW(4), VIC(5), TAS(6)
and SA(7) respectively; sections 8-16 are internal mainland state
boundaries: SA-WA(8), WA-NT(9), NT-SA(10), NT-QLD(11), QLD-SA(12),
QLD-NSW(13), NSW-SA(14), NSW-VIC(15), VIC-SA(16).)
ARG(visible @@ integer vector specifying which of the sections are
actually to appear on the plot.)
ARG(... @@ optional arguments which will be passed through LANG(lines).)

Graphical parameters (see LANG(par())) may also be supplied as arguments
to this function.)
EXAMPLES(
oz()                    # the lot
oz(states=F)            # coastlines only
oz(sections=6)          # Tasmania
oz(sections=c(7,8,10,12,14,16))         # South Australia
oz(sections=c(3,11:13), visible=c(3,13))# plot Queensland, but show just
                                        # coast and border with NSW.
