[R] simple example for linear mixed effects model
Dear R Gurus: Could someone point me to a small example of a linear mixed effects model, please? Ideally, this example would only have a few data points so I could calculate by hand to compare results to R results, please. Thanks so much! Sincerely, Edna Bell __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
[R] classes and methods
I have put together a test class and methods
> setClass("foo",representation(x="numeric"))
[1] "foo"
> setMethod("plot","foo",function(x,y,...)boxplot(x,...))
[1] "plot"
> x <- rnorm(100)
> class(x) <- "foo"
> plot(x)
> y <- new("foo",x=rnorm(50))
> class(y)
[1] "foo"
My question is: should I have a "foo" function which sets the class
to "foo", please? or a sort of Validity checker, please?
Thanks,
Edna Bell
