type III ANOVA for a nested linear model
Hello, is it possible to obtain type III sums of squares for a nested model as in the following: lmod <- lm(resp ~ A * B + (C %in% A), mydata)) I have tried library(car) Anova(lmod, type="III") but this gives me an error (and I also understand from the documentation of Anova as well as from a previous request (http://finzi.psych.upenn.edu/R/Rhelp02a/archive/64477.html) that it is

attributes on symbols
The multcomp package has code in multcomp:::expression2coef that attaches the 'coef' attribute to symbols. Since there is only one symbol object in a session with a given name, this means that this attaching has a global effect. Should this be quietly allowed or should there be a warning or an error? E.g., str(quote(Education)) # symbol Education lmod <- stats::lm(Fertility ~ .,

attributes on symbols
Thanks for spotting this issue. The short answer is yes, adding attributes to a symbol is a bad idea and will be turned into a runtime error soon. Maintainers of packages that add attributes to symbols have been notified and some have already fixed their code. At least in one case the package is not working properly, even in isolation, because of the global effect of adding an attribute to a

problem with eval(..., parent.frame(1L)) when package is not loaded
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 The lmer() function in the lme4 package has some code of the form mc <- match.call() mc[[1]] <- as.name("lFormula") lmod <- eval(mc, parent.frame(1L)) this is a fairly common idiom in R, found e.g. in lm(), used when one wants to pass all of the arguments of a function to a different function (in the case of lm() it's

calcMin
I tried to use calcMin with a function that uses a number of ... arguments (all args from resid on) besides the vector of parameters being fit. Same idea as optim, nlm, nlminb for which this form of ... syntax works. But with calcMin I get an error regarding unused arguments. No partial matches to previous arguments that I can see. Anybody know the reason or fix for this?
