| lines.density.circular {circular} | R Documentation |
The lines add a plot for density.circular objects.
## S3 method for class 'density.circular':
lines(x, type = "l", zero.line = TRUE, points.plot = FALSE, points.col = 1, points.pch = 1, points.cex = 1, plot.type = c("circle", "line"), bins = NULL, shrink = 1, tcl = 0.025, sep = 0.025, join = TRUE, nosort = FALSE, plot.info = NULL, zero = NULL, rotation = NULL, ...)
x |
an object of class density.circular. |
type |
plotting parameter with useful default. |
zero.line |
logical; if TRUE, add a base line at y =
0. Used when plot.type is "line". |
points.plot |
logical; if TRUE original data are added to
the plot. |
points.col, points.pch, points.cex |
parameters used to draw the points. |
plot.type |
type of the plot. |
bins |
number of ticks to plot. |
shrink |
parameter that controls the size of the plotted circle. Default is 1. Larger values shrink the circle, while smaller values enlarge the circle. |
tcl |
length of the ticks. |
sep |
constant used to specify the distance between stacked points. Default is 0.025; smaller values will create smaller spaces. |
join |
logical: should the first and the last point joined. |
nosort |
logical: should the data sort before plotting. Defaults is to sort. |
plot.info |
an object from plot.circular that
contains information on the zero, the rotation and next.points. |
zero |
the zero of the plot. Ignored if plot.info is provided. |
rotation |
the rotation of the plot. Ignored if plot.info is provided. |
... |
futher parameters passed to lines.default. |
A list with information on the plot: zero, rotation and next.points.
