RE: [R] Required Packages etiquette

[This is probably more appropriate for R-devel rather than R-help.] IMHO the criterion for requiring a package (say `X') is that, if some function(s) in your package can not perform its tasks correctly without something in `X', then you should list `X' as required. You can not assume the user wil

[R] Anova - interpretation of the interaction term

Hi So carrying on my use of analysis of variance to check for the effects of two factors. It's made simpler by the fact that both my factors have only two levels each, creating four unique groups. I have a highly significant interaction term. In the context of the experiment, this makes sense.

[R] Help needed with lattice graph!

Dear R users, If I manage to sort out this graph, it is certainly a candidate for the new R graph gallery (http://addictedtor.free.fr/graphiques/displayGallery.php)! I created the following lattice graph: library(lattice) tmp <- expand.grid(geology = c("Sand","Clay","Silt","Rock"), species =

Re: [R] pointer to comments re Paul Murrell's new book, R, & SAS on Andrew Gelman's blog

Brief comment on blog. S Plus is mentioned only in passing. I've always thought comparisons between SAS and R are invalid as they do different things. If I wasn't using R I'd be coding in either C or Fortran. SAS appears to be a database with statistical functionality attached. I've always th
