[R] draw partition lines

[Greg Snow]

Here is one approach (you can adapt as needed):

library(TeachingDemos)

par(mfrow=c(4,2))

plot(1:10)
plot(10:1)
plot(c(1:5,5:1))
plot(c(5:1,1:5))

tmp <- cnvrt.coords(1,0, input='fig')$usr # get right end coord
tmp2 <- cnvrt.coords(0,NA, input='tdev')$usr # get left end 
par(xpd=NA) # turn off clipping
segments(tmp$x,tmp$y,tmp2$x,tmp$y, col='blue')

hist(rnorm(10))
hist(rnorm(100))
hist(rnorm(3))
hist(rnorm(10000))

Hope this helps,
