I don't have a copy of SV4 (or SV3, where model.frame was introduced), but S+ 8.3 (based on SV4) puts the class "model.frame" on model.frame()'s return value but has no methods (in the default packages) for class "model.frame". Perhaps that is why R omitted the class. However, S+ 8.3's (and problably S's) formula.data.frame did look for a "terms"

Dear Martin, Since no one else has picked up on this, I?ll take a crack at it: The proposal is to define the S3 class of model-frame objects as c(?model.frame?, ?data.frame?) (not the formal class of these objects, even though this feature was coincidentally introduced in S4). That?s unlikely to do harm, since model frames would still ?inherit? data.frame methods. It's possible that some

When formula() is applied to the output of model.frame() it ignores the formula in the model.frame's 'terms' attribute: > d <- data.frame(A=log(1:6), B=LETTERS[rep(1:2,c(2,4))], C=1/(1:6), D=rep(letters[25:26],c(4,2)), Y=1:6) > m0 <- model.frame(data=d, Y ~ A:B) > formula(m0) Y ~ A + B > `attributes<-`(terms(m0), value=NULL) Y ~ A:B This is in part

Dear R-helpers: My question is how do I efficient and valid correct for multiple tests in a repeated measurement design: Suppose we measure at two distinct visits with repeated subjects a treatment difference on the same variable. The treatment differences are assessed with a mixed model and adjusted by two methods for multiple tests: # 1. Method: Adjustment with library(multcomp)

Dear R-Developers, The traffic today on s-news where Terry Therneau, I, and others are reporting some of the problems we have had using or converting applications to SV4 reminded me of something Duncan Temple Lang had mentioned to me a year ago that I wanted to follow up on. I recall that Duncan said either that if SV4 were to be implemented in R that it would not be the default behavior, or

No. One use for setting mfg is to produce a page of plots in portrait orientation with, say, two small plots on the top half of the page

Hello, I am looking for an explanation and/or fix for a discrepancy in the behaviour of the R lm.influence() function [ version R 1.5.0 (2002-04-29) ] and the same function in Splus [ Splus version 5.1 release 1, running on SGI IRIX 6.2]. The discrepancy is of concern because I am migrating some Splus scripts to R and need to ensure consistency of results. Specifically, when I fit a glm()

Chris, I can provide some personal experience, in that RedHat Linux has not only operated well, and is remarkably easy to set up, but seems to work as well as any Linux distribution with R. The default X-Windows setup looks pretty similar to MS Windows, which may make the transition easier. In fact, it was the on/off - finally off attitude of MathSoft toward producing a Linux version of S-Plus

Kurt, here's what S does (I recall going to some effort to duplicate the, at times, seemingly unusual behaviour of cat) S-PLUS : Copyright (c) 1988, 1996 MathSoft, Inc. S : Copyright AT&T.

> I'm not necessarily sympathetic to the idea of adding another canonicalization pass only for this purpose. The problem is that as you said, SimplifyCfg does all sorts of stuff, and I suspect is not the fastest pass in the world. Also, in the case that annoys me, there is an LCSSA pass in the middle, and I suspect it would be a better idea to only do the LCSSA etc. transform again if no

I think this goes back to SV4 (c. late 1990's). The is.<type> functions are much older (c. mid 1970's) , from before any class system was in S. is() and inherits() were introduced with the S4 class system and were meant to escape from the prison made by ancient design choices.
