dotcircle

Representation of n values on a circle

Description

This function represents n values on a circle. The n points are shared out regularly over the circle and put on the radius according to the value attributed to that measure.

Usage

dotcircle(z, alpha0 = pi/2, xlim = range(pretty(z)),
 labels = names(z), clabel = 1, cleg = 1)

Arguments

`z`	: a numeric vector
`alpha0`	: polar angle to put the first value
`xlim`	: the ranges to be encompassed by the circle radius
`labels`	: a vector of strings of characters for the angle labels
`clabel`	: a character size for the labels, used with `par("cex")*clabel`
`cleg`	: a character size for the ranges, used with `par("cex")*cleg`

Examples

w <- scores.neig(neig(n.cir = 24))
par(mfrow = c(4,4))
for (k in 1:16) dotcircle(w[,k],labels = 1:24)
par(mfrow = c(1,1))
