This example is caused by R's messing with formula environments. That's explained in ?formula, but should it not be explained in ?model.frame ? Simple test: data <- data.frame(y=rnorm(100), x=1:100) testit <- function(formula) { weights <- runif(100) glm(formula, weights=weights, data=data) } testit(y ~ x) weights is looked for in the environment of the formula, not of

[Copied to R-devel for information] This applies to all versions of R I have: 0.62.2, 0.62.3, 0.63. Great care seems needed with glms with offsets, as many things seem wrong.

Hi, I'm currently writing an S4/Oracle interface, and as Brian Ripley points out, the .Call interface is the key. The good news is that the S part (I presumed the R part as well) is remarkably straight- forward by using the .Call facilities to create list and other S objects directly from C. I'm following Brian's suggestion and printing the R-external documentation --- I need to

anova() on three or more objects behaves inconsistently in R. In R anovalist.lm does a sequential ANOVA using pairwise F tests, ignoring all the other objects, so the larger of the two models provides the denominator. In S anova.lmlist uses the denominator from the largest model (smallest residual df) in the set, as does anova.glmlist in both. I suggest that R's anovalist.lm is wrong (that

Since this works in recent S-PLUS and is not in the FAQ as a difference, I presume it is an unintentional one. If it is intentional, this is for the wishlist that this be removed.

Hi to R developers. In the "Details:" section of "?levels", it would be nice including the following sentence, taken from a reply from Brian Ripley: If you set two levels to be the same label, they get merged. Granted, the "Examples:" section does have a terse comment and examples from which users may imply this behaviour. Yet, the documentation would be

There's more to it than that (which was already fixed in R-devel). The internal code expects there to be columns in the model frame. I have already fixed this in R-devel (by faking an unused column).

I suspect Prof. Ripley's response suffices. However, there *is* a Parzen kernel for kernel smoothing: Parzen K(z) = { 4/3 - 8z^2 + 8|z|^3 if |z| <= 1/2 8(1 -|z|)^3/3 if 1/2 < |z| <= 1 0 otherwise If I'm not mistaken, this appeared in Parzen's original 1962 paper on kernel density estimation. I also seem to recall
