R-devel,
I'm interested in looking at some examples of existing R packages that
rely heavily on S4 classes to get a feel for varying styles and
package organization techniques. Could you recommend any packages
that might serve as a good starting point?
Thanks in advance,

Hi,
The following patch cleans up some grammar in the docs for UseMethod
(library/base/help/UseMethod)

Here's my entry for Vectorize:
Vectorize <- function(FUN, vectorize.args = names(fargs)) {
fargs <- formals(FUN)
dovec <- match(vectorize.args, names(fargs))
FUNV <- function() { # will set the formals below
args <- as.list(match.call())[-1]
args <- lapply(arg

When I read the preface to The Blue Book (The New S Language, Becker,
Chambers & Wilks) I see comments along the lines of "high-level
language", "primary goal of the S environment is to enable and encourage
good data analysis", etc. While vectorization is a great feature of S
