clock24.plot: Plot values on a 24 hour "clockface"

In plotrix: Various Plotting Functions

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.

If ‘⁠add=TRUE⁠’ is passed as one of the additional arguments, the values will be added to the current plot. If a ‘⁠radial.lim⁠’ argument was passed on the initial plot, it must be passed again to add values or the values will be displayed incorrectly.

Usage

 clock24.plot(lengths,clock.pos,labels=0:23,minutes=FALSE,
  hm2dec=FALSE,label.pos=NULL,rp.type="r",loglen=FALSE,explab=FALSE,...)

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.
minutes	Whether to add minutes (".00") to the labels.
hm2dec	Whether to convert HH:MM clock positions to decimal hours.
label.pos	Radial positions of the labels.
rp.type	Whether to plot radial lines, symbols or a polygon.
loglen	Whether to log transform the ‘⁠length⁠’ values. Only base 10 logs are available.
explab	Whether to use the default fixed (FALSE) or exponential (TRUE) notation for the radial labels.
...	additional arguments are passed to ‘⁠radial.plot⁠’ and then to ‘⁠plot⁠’.

Value

A list of the parameters altered by radial.plot.

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
 oldpar<-clock24.plot(testlen[7:19],testpos[7:19],
  main="Test Clock24 daytime (symbols)",
  point.col="blue",rp.type="s",lwd=3)
 # reset everything
