Add a Plot for Kernel Density Estimation for Circular Data
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, offset=1, shrink = 1,
tcl = 0.025, sep = 0.025, join = TRUE, nosort = FALSE,
plot.info = NULL, zero = NULL, rotation = NULL, ...)x |
an object of class |
type |
plotting parameter with useful default. |
zero.line |
logical; if |
points.plot |
logical; if |
points.col, points.pch, points.cex |
parameters used to draw the points. |
plot.type |
type of the plot. |
bins |
number of ticks to plot. |
offset |
the radius of the circle |
shrink |
parameter that controls the size of the plotted function. Default is 1. |
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 |
zero |
the zero of the plot. Ignored if |
rotation |
the rotation of the plot. Ignored if |
... |
futher parameters passed to |
A list with information on the plot: zero, rotation and next.points and, if available, the coordinates x and y.
