R help - Jul 2010 - possible to plot number line in R?

Hallo!

Is there a possibility to plot a number line in R?
I would like to display 3 different Intervals on the same number line. Ideally,
it would be possible to add a name to each number (e.g. Interval 1, lower
cut-off...and so on). I have not found a command for this.

Thank you for your help.

Do provide an example of the data and what you what to do with it.

What is the problem that you are trying to solve?

Here is a simple 'brute force' way to do it (assuming I understand what
you want)
=================================================================text1 <-
"Interval 1"
text2 <- "Inteval 2"
text3 <-  "Interval 3"
ycord <- 3.3

plot(1:21, rep(3,21), type="l", xlab="Number Line",
ylab="",yaxt="n")
arrows(c(7.5,14.5),c(2.8,2.8), c(7.5,14.5),c(3.2,3.2), length=0)
text(4, ycord, labels=text1, cex=.75)
text(11, ycord, labels=text1, cex=.75)
text(18, ycord, labels=text1, cex=.75)
=====================================================================

Hi Julia,
I had to do a tweak on the spread.labels function (attached). Try this:

library(plotrix)
source("spread.labels.R")
plot(0:100,axes=FALSE,type="n",xlab="",ylab="")
axis(1,pos=0)
spread.labels(c(5,20,50,60,70,90),rep(0,6),ony=FALSE,
 
labels=c("Bottom1","Top1","Bottom2","Top2","Bottom3","Top3"),
  offsets=rep(20,6))

Jim

Thank you very much for your answers, but I think I did not explain thoroughly
enough what I needed. I attached a demo of the plot. I need the number line
between 2 and 3, both values being shown on the line, interval values should be
printed next to the dashes and lines should connect the intervals.

Is this possible to do in R?



Best Regards,

Julia
