[R] possible to plot number line in R?

[John Kane]

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)
======================================================================
