Quantile-Quantile Linearised Plot for Circular Distributions
Description
Uniformly distributed orientations should yield a straight line through the origin. Systematic departures from linearity will indicate preferred orientation.
Usage
circular_qqplot(
x,
axial = TRUE,
xlab = paste("i/(n+1)"),
ylab = NULL,
main = "Circular Quantile-Quantile Plot",
add_line = TRUE,
col = "#B63679FF",
...
)
Arguments
x |
numeric. Angles in degrees |
axial |
Logical. Whether data are uniaxial ( |
xlab , ylab , main |
plot labels. |
add_line |
logical. Whether to connect the points by straight lines? |
col |
color for the dots. |
... |
graphical parameters |
Value
plot

Examples
# von Mises distribution
x_vm <- rvm(100, mean = 0, kappa = 2)
circular_qqplot(x_vm, pch = 20)
x_norm <- rnorm(100, mean = 0, sd = 25)
circular_qqplot(x_norm, pch = 20)
# uniform (random) data
x_unif <- runif(100, 0, 360)
circular_qqplot(x_unif, pch = 20)
