Often called an `index plot'. It's done by plot(type="h"). R seems to think that is `histogram-like', but the notation comes from S which calls it `high-density lines'. I've never found either intuitive notation. > Can anyone give me pointers on where to look for more info.

I suspect it was done by plot.lm(which=4), which does an index plot of Cook's distance. -- Brian D.
