setClass created an S4 class, not an S3 class, and classes are not
objects (so don't try to use it in package.skeleton). [*]
Are you going to have "buzz" methods for S4 generics? If not, you
don't need the setClass line. If you do, you need to put the line
yourself in an R file in the package skeleton, one that will be
sourced before anything which makes use of it (e.g. file AAA.R).
[*] Well, currently creating that class creates object .__C__buzz, but
if you use package.skeleton without a list, you get
Warning message:
In dump(internalObjs, file = file.path(code_dir, sprintf("%s-internal.R", :
deparse of an S4 object will not be source()able
and that object is .__C__buzz.

Hi List!
Suppose I have the following, please:
setClass("buzz",representation(x="numeric"),S3methods=TRUE)
[1] "buzz"
x <- rnorm(10)
class(x) <- "buzz"
plot.buzz <- function(x,y,...) {
+ plot.default(x,type="l",col="blue")
+ }
f <- function(x) {
+ return(x^2)
+ }
package.skeleton(list=c("buzz","plot.buzz","f"),name="test1")
Creating directories ...
Creating DESCRIPTION ...
Creating Read-and-delete-me ...

Done.
Further steps are described in './test1/Read-and-delete-me'.
Warning message:
In package.skeleton(list = c("buzz", "plot.buzz", "f"), name = "test1") :
object ''buzz'' not found
How can I bring the class "buzz" into the new package, please?
Thank you!
