The y axis on the hist function seems to set its limits oddly. sometimes, it covers the full range of the data and sometimes it stops one major tick short. I have had this behavior with a variety of data sets, and it can easily be reproduced by just running the following several times:
hist(rnorm(100000))
If you use instead: hist(rnorm(100000)); box() You won't notice anything strange, and you may be satisfied with the result. The `problem', if there is a problem, is pretty deep in the command axis() used by histogram plotting function plot.histogram(), and the behaviour is just same as in other R graphs which do not necessarily have tic marks at the axis extremes. You can see if you execute sequentially: plot(rnorm(100), rnorm(100), axes=FALSE) axis(1); axis(2) box() So it's a property, and using box() is the easiest way to hide this property, if you don't like it. cheers, jari oksanen
