Re: [R] ANOVA plotting

I recently started using R and I have a simple question. I am running R (v. 2.12.1) and Rcmdr (v.1-6.3) on Mac (Snow Leopard). I am using a data set I used before for practicing ANOVA with R, so I know what the results should look like. I can get ANOVA table using both Rcmdr and GUI. However,

Re: [R] how can I plot bar plots with all the bars (negative and positive) in the same direction????

As is often the case in R, just because you shouldn't do something, doesn't mean you can't do it. Still, I'd urge you to consider the "visual honesty" of what you propose. If you're still insistent: dat <- (-3:4) dat1=dat-min(dat) barplot(dat1,axes=FALSE) axis(2,dat1,labels=dat) Typically, ze

Re: [R] how can I plot bar plots with all the bars (negative andpositive) in the same direction????

It occurred to me after my initial post that you will need a little more "fixing" of your axis labels if you have data that is not trivial integers as in your example. Consider the following solution for some irrational random numbers: dat=rnorm(20) dat1=dat-min(dat) barplot(dat1,axes
