clock24.plot {plotrix}R Documentation

Plot values on a 24 hour "clockface".

Description

clock24.plot displays a plot of radial lines, symbols or a polygon centered at the midpoint of the plot frame on a 24 hour 'clockface'. In contrast to the default behavior of radial.plot, the positions are interpreted as beginning at vertical (000) and moving clockwise.

Usage

 clock24.plot(lengths,clock.pos,labels=NULL,label.pos=NULL,rp.type="r",...)

Arguments

lengths numeric data vector. Magnitudes will be represented as line lengths, or symbol or polygon vertex positions.
clock.pos numeric vector of positions on the 'clockface'. These must be in decimal hours and will be rescaled to radians.
labels Labels to place at the circumference.
label.pos Radial positions of the labels.
rp.type Whether to plot radial lines, symbols or a polygon.
... additional arguments are passed to radial.plot and then to plot.

Value

nil

Examples

 testlen<-rnorm(24)*2+5
 testpos<-0:23+rnorm(24)/4
 clock24.plot(testlen,testpos,main="Test Clock24 (lines)",show.grid=FALSE,
  line.col="green",lwd=3)
 if(dev.interactive()) par(ask=TRUE)
 # now do a 'daylight' plot
 clock24.plot(testlen[7:19],testpos[7:19],
  main="Test Clock24 daytime (symbols)",
  point.col="blue",rp.type="s",lwd=3)
 # reset the margins
 par(mar=c(5,4,4,2))
