x |
a vector, matrix or data.frame. The object is coerced to class |
pch |
point character to use. See help on |
cex |
point character size. See help on |
axes |
logical: if |
shrink |
parameter that controls the size of the plotted circle. Default is 1. Larger values shrink the circle, while smaller values enlarge the circle. |
bins |
number of arcs to partition the circle with. |
upper |
therose diagram cells are "upper"-closed intervals. |
ticks |
logical: if |
tcl |
length of the ticks. |
tcl.text |
the position of the axis labels. |
radii.scale |
make possible to choose sector radius form:
square-root of relative frequency ( |
border |
the color to draw the border. The default, |
col |
the color for filling the rose diagram. The default,
|
tol |
proportion of white space at the margins of plot. |
uin |
desired values for the units per inch parameter. If of length 1, the desired units per inch on the x axis. |
xlim , ylim |
the ranges to be encompassed by the x and y axes. Useful for centering the plot. |
prop |
numerical constant determining the radii of the sectors. By default, prop = 1. |
digits |
number of digits used to print axis values. |
plot.info |
an object from |
units |
the |
template |
the template of the plot. Ignored if |
zero |
the zero of the plot. Ignored if |
rotation |
the rotation of the plot. Ignored if |
main , sub , xlab , ylab |
title, subtitle, x label and y label of the plot. |
add |
add the rose diag to an existing plot. |

The circumference of the circle is split into groups, the number of groups specified by bins. For each group, a sector is drawn. The radii of the sectors are by default equal to the square root of the relative frequencies of observations in each group. This ensures that the area of the sector is proportional to the group frequency. The length of the radii can be controlled by varying the parameter prop. Since version 0.3-9 the intervals are on the form [a,b).
a list with information on the plot: zero, rotation and next.points.
some codes from eqscplot
in MASS is used. Since
version 0.4-1 the meaning of the col
parameter is changed.
