R devel - Jun 2015 - S3 internal and group generics

Hi all,

I've noticed a couple of small bugs/documentation errors related to S3
internal and group generics:

* In ?S3groupGeneric, log2 and log10 are not listed as group generics,
even though they are in the equivalent S4 groups, and are the source
code for do_log1arg contains DispatchGroup("Math", ...)

* As well as log2 and log10, tools:::.get_internal_S3_generics() fails
to include cbind and rbind, even though they are listed in ?"internal
generics"

Based on my reading of the documentation and the source code, I
believe this function lists all S3 internal generics:

s3_internal <- function(fname) {
  # Functions in S4 group generics should be the same
  group <- c(getGroupMembers("Arith"),
getGroupMembers("Compare"),
    getGroupMembers("Logic"), getGroupMembers("Math"),
getGroupMembers("Math2"),
    getGroupMembers("Summary"), getGroupMembers("Complex"))

  primitive <- .S3PrimitiveGenerics

  # Extracted from ?"internal generic"
  internal <- c("[", "[[", "$",
"[<-", "[[<-", "$<-", "unlist",
    "cbind", "rbind", "as.vector")

  c(group, primitive, internal)
}

Have I missed anything?

Thanks!

I have found the following generics which your function did not inlcude.1]
"as.character.default"  "as.expression.default"
"as.list.default"
"as.name"              [5] "as.pairlist"          
"as.single.default"
"as.symbol"             "body<-"               [9]
"kronecker" I used the
following code:base_objs              <-
objects("package:base")base_function        <-
mapply(function(x)ftype(get(x)), base_objs)base_objs_generic <-
base_objs[grep("generic",base_function)]

and is mangled because you've post via Nabble which may always
use HTML.

I'd really us to consider **banning** the use of Nabble for
R-devel, completely.  People on this list should be able to
subscribe to a mailing list and deal with mail filtering etc...
