S3 method dispatch for methods in local environments
Dear All,
In R 3.6.3 (and earlier), method dispatch used to work for methods stored in local environments that are attached to the search path. For example:
myfun <- function(y) {
out <- list(y=y)
class(out) <- "myclass"
return(out)
}
print.myclass <- function(x, ...) print(formatC(x$y, format="f", digits=5))
myfun(1:4)
# prints: [1]

smooth: differences between R and S-PLUS
Hi!
I am studying differences between R and S-PLUS smooth() functions. I know
from the help that they worked differently, so I ask:
- exist a package that permit to have the same results?
- alternatively, someone know how can I obtain the same results in R, using
a self made script?
I know that S-PLUS use the 4(3RSR)2H running median smoothing and I try to
implement it with the code below. I

help with predict for cr model using rms package
Dear list,
I'm currently trying to use the rms package to get predicted ordinal
responses from a conditional ratio model. As you will see below, my
model seems to fit well to the data, however, I'm having trouble
getting predicted mean (or fitted) ordinal response values using the
predict function. I have a feeling I'm missing something simple,
however I haven't been able to

Summary statistics for matrix columns
Hi,
is there a way I can calculate a summary statistics for a columns matrix
let say we have this matrix
x <- matrix(sample(1:8000),nrow=100)
colnames(x)<- paste("Col",1:ncol(x),sep="")
if I used summary
summary(x)
i get the output for each column but I need the output to be in matrix with
rownames and all the columns beside it

S3 method dispatch for methods in local environments
Dear Wolfgang,
I think this new behaviour is related to the following R 4.0.0 NEWS item:
> S3 method lookup now by default skips the elements of the search path between the global and base environments.
Your environment "myenv" is attached at position 2 of the search() path
and thus now skipped in S3 method lookup.

Confidence intervals for Sen slope in zyp-package
Hi,
I have a question about the computation of confidence intervals in the zyp package, in particular using the functions zyp.sen and confint.zyp, or zyp.yuepilon.
(1) I'm a bit confused about the confidence intervals given by zyp.sen and confint.zyp. When I request a certain confidence interval in the function, the R output seems to deliver another confidence interval, e.g. when I set

adonis (vegan package) and subsetted factors
Hi,
I'm trying to use adonis on a subset of data from a dataframe. The
actual data is in columns 5:118, and the first four columns are various
factors. There are 3 levels of the factor Habitat, and I want to examine
differences among only two of them. So I started with:
> CoastNear = subset(gel_data, Habitat != "I")
The resulting data.frame has three levels for Habitat, but

I am performing a two-way ANOVA (2 factors with 4 and 5 levels,

then the interaction between both factors is significant:

Moving window regressions - how can I improve this code?
I wrote a function which does "moving window" regressions. E.g. if
there are 100 observations and the window width is 50, then I first
run the regression for observations 1..50, then for 2..51, and so on.
I am extremely pleased with R in my experience with writing this,
since I was able to pass the model as an argument into the function
:-) Forgive me if I sound naive, but that's

which alternative tests instead of AIC/BIC for choosing models
Dear R Users,
I am looking for an alternative to AIC or BIC to choose model parameters.
This is somewhat of a general statistics question, but I ask it in this
forum as I am looking for a R solution.
Suppose I have one dependent variable, y, and two independent variables,
x1 an x2.
I can perform three regressions:
reg1: y~x1
reg2: y~x2
reg3: y~x1+x2
The AIC of reg1 is 2000, reg2 is
