Number of square. If number of square >1000 the last digit
means subsquare. For example 5604 means square 560, subsquare 4.
smareitur
Number of subsquare if they are used. Default is that
subsquare is not used.
z
Values for each square and subsquare.
levels
Values between colors or different density of lines. Default
is to let the program find it. A small example shows how levels are given.
<s-example>
levels <- c(0, 100, 1000, 2000, 4000, 5000, 8000)
</s-example> Then the groups are <100, 100-1000, 2000-4000, 4000-5000 &
>5000, i.e. the program more or less ignores the first and the last values
given.
colors
Number of color or shading pattern for each level. Colours
can go from 0 thru 155. They go from white = 0, black = 1, blue = 2, green,
yello, red = 155. Density goes from 10 thru 130. Everything above 130 is
completely black. If colors is not given the program determines it from the
data. Default maximum density is set to 70 but everything above that is
very black.
density
If density is 0 coloured plot is made else different desity
of lines is used.
maxcol
Maximum color ( or density) Default value is 155 for colors 70
for shading. All density of lines > 130 are black.
nlevels
Number of levels. Default value is 6.
white
If white = TRUE the lowest color or density is zero. Default
value is white.
border
If border of polygon is to be drawn. Default value is FALSE.
angle
Angle of lines used for hatching. Default value is 45 degrees.
rotate
Rotation of hatcing lines between each level. Default value
is zero or no rotation but rotate = 90 is very useful.
digits
Number of digits in labels. Default value is zero.
cex
Charcter expansion of digits in labels. Default value is the
current size when the program is called.
label.location
location of labels, default is no labels are plotted.
labels.only
if true only labels are plotted.
col
the color of lines, default is 1 (black).
outside
if true squares outside plot area are plotted, default is
true.
mincol
the color number of the first color to be used, colors are
taken from the range mincol to maxcol.
Details
Geoplot has to be called before to set the parameter geopar. If geoplot is
called with the parameter cont = TRUE labels are plotted on the left hand
side of the plot. If a color plot is to be made litaps has to be called
before.
