Hi: 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...

Hi: I am running lattice 0.6-6 with grid 0.7-2 on RH 7.3 using the binary version of R 1.6.1 from CRAN. If I use a key with lines in it, anytime I try...

Well, it seems my hard won workaround was documented after all. Wouldn't it be nice if this were in the as.numeric help page? Look, I haven't slacked off. I have the Ripley and Venables book (in fact...

Recently, I was using aggregate() to develop averages by trial for an experiment I was running. Trials were indicated as ordinal numbers for each subject. aggregate() turned trial into factors during the aggregation process. I then wanted to create a...

Let me try to clarify. I would like an automated way to set the y axis to cover the largest count (or density) in one of the automatically computed bins. I thought hist did this. Working from Dalgaard's book...

Thanks! I wondered if something like this was not going on, but could not figure out how to get to the root of it. BTW, your book is very good. Have you considered writing an intro or intermediate programming R...

Thanks for the clarification. It's nice to know that there is some systematicity to the behavior. Is this documented anywhere? I did look at the help for as.numeric, and it makes no mention that it is coercing factors...

The behavior makes more sense now but is in need of clarification in the help files. Specifically, aggregate should mention that it is converting arguments to characters. Factoring a numeric vector leads to what you might expect, factors ordered numerically...
