[R] Label multiple-line plot

[Greg Snow]

with 72 lines to label it will be crowded whatever you do.

Here is one option (though I am showing with fewer lines):

x <- sapply(1:15, function(i) cumsum(rnorm(100)))
par(mar=c(5,4,4,3)+0.1)
matplot(1:100, x, type='l', lty=1)
mtext(LETTERS[1:15], side=4, at=x[100,], las=1, line=1)

One way to spread out the labels is:

library(TeachingDemos)
new.y <- spread.labs(x[100,], mindiff = 1.2*strheight('A'),
                     min=min(x), max=max(x))
mtext(LETTERS[1:15], side=4, at=new.y, las=1, line=2)


There is also another label spreading function in the plotrix package
and another option for finding space in a plot for labeling lines in
either the rms or Hmisc package.  There are probably other packages
with tools available now as well, but those are the ones that I am
familiar with.
