| oz {oz} | R Documentation |
Plot the Australian coastline and states.
oz(states = TRUE, coast = TRUE, ar = 1, eps = 0.25) oz(xlim = c(113, 154), ylim = c(-44, -10)) oz(sections) oz(sections, visible) oz(..., add)
states |
logical flag: include mainland internal state boundaries? |
coast |
logical flag: include coastline? |
xlim |
optional limits for the x-axis (longitude). |
ylim |
optional limits for the y-axis (latitude). (N.B. all latitudes for Australia are south, and hence are NEGATIVE.) |
add |
logical flag. If TRUE, the plot is superimposed on an existing plot. Otherwise, a new plot is generated. |
ar |
aspect ratio: longitude to latitude. |
eps |
If sections (q.v.) is specified explicitly, the plot
is enlarged four ways by this amount (degrees). |
sections |
integer vector specifying which 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). |
visible |
integer vector specifying which of the sections are actually to appear on the plot. |
... |
optional arguments which will be passed through
lines. |
Graphical parameters (see par()) may also be supplied as
arguments to this function.
ozRegion returns an object of class "ozRegion",
which is a list with the following elements:
rangex and rangey,
giving the range of values to be plotted; and lines,
a list of lists, where each sub-list describes a line to draw
via numeric elements x and y.
oz() # the lot
oz(states=FALSE) # 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.
