I agree that it would make sense for the object to have c("by", "list") as
its class attribute, since the object is known to behave as a list.
However, it would may be too disruptive to make this change at this point.
Hard to predict.

by() does not always return a list. In Gabe's example, it returns an
integer, thus it is coerced to a list. as.list() means that it should be a

I pretty much agree. I tried using roxygen when it was first released but
couldn't stand putting documentation in comments, especially for complex,
S4-based software. Rd is easy to read and write and lets me focus on the
task of writing documentation (focus is the hardest part of any task for
me).
The issue should be resolved in R-devel. It was actually deeper and more
important than this obscure insertSource() function. names() was not doing
the right thing on S4 objects derived from "environment".

Folding is a simple solution, but there are intrinsic problems, like the
need to embed the documentation in comments. If the user already has to
expand a fold to edit the docs, the IDE could instead just provide a link

My understanding is that array (or any other structure) does not
"simply" inherit from vector, because structures are not vectors in
the strictest sense. Basically, once a vector gains attributes, it is
a structure, not a vector. The methods package accommodates this by
defining an "is" relationshi

doing anything about them at this point.

Actually, it's sort of the opposite. Everything becomes a sequence of

While it's easy to conceive of a utility that found all generics for
which there is no non-default method for a given class vector, it's
not clear it would be useful, because it depends on the nature of the

it is not, consider "foo <-
A generic function is not simply a way to name two functions (methods)
the same. It has a particular purpose, and the argument names are
aligned with and convey that purpose. The methods only implement
polymorphism; they don't change the purpose. Changing the purpose

Whenever they are calling a primitive, because primitives match
arguments positionally. Of course, you then you need to introduce the
concept of a primitive.
You could also make an argument from the code clarity perspective, as
typically primitives have simple interfaces and/or are used frequently
Argument matching is by name first, then the still missing arguments
are filled positionally. Unnamed missing arguments are thus left
missing. Does that help?

Just to clarify, primitive (C-level) generics do not support dispatch
on basic classes (like character). This is for performance (no need to
consider dispatch on non-objects) and for sanity (in general,
redefining fundamental behaviors is dangerous). It is of course

Probably need a generic tree based on "ParseNode" objects that
associate the line information with the symbol (for leaf nodes). As
Duncan notes, it should be possible to gather that from the table.
But it would be nice if there was an "expr" column in the parse data
column in addition to "text". I
ere one would want a reference from parse node to location.
So neither of those involves code evaluation at first glance, though I
guess one could use some sort of evaluation during analysis.

The first two behave as expected for vectors, because they are both
(at least implicitly) vectors in that usage. But a data.frame is a
tabular structure, so it's not obvious how to recycle it, nor does an
implicit coercion to matrix/vector seem justified. Thus, R attempts to
"recycle" the vector to

Yes, functions like c, min and max are special cases, as they are

Thanks for pointing this out. The commit you cite was reverted a couple
days later, because we are still thinking about how it should work. While
it appears Date would benefit, weird things happen e.g. with POSIXlt and
other data structures in the wild. This is due to inconsistency in the
behaviors
Right, the methods package is not attached by default when running R
with Rscript. We should probably remove that special case, as it
mostly just leads to confusion, but that won't happen immediately.
For now, the S4_extends() should probably throw an error when the
methods namespace is not loaded

I was looking into making sub-assignment into atomic vectors work when the
value is an S4 object. The plan was to simply dispatch to an as.vector
method and proceed as normal.
Currently, if 'x' is a list, then any S4 'value' is first wrapped in a list.

The radix sort should be consistent with the others, i.e., it should
behave like sort.list(), not order(). I will correct this.

One option would be to use the same strategy that we use for cbind()
and rbind(), i.e., if dispatch fails, call a binary generic, c2(),
recursively. Could do the same for pmin() and pmax().

Thanks for the suggestion. Checked in that change.

Hi Bill,
Thanks, another good suggestion. strcapture() now returns NAs for
non-matches. It's nice to have someone kicking the tires on that
function.

The issue with as.character.factor() was reported and fixed recently.
https://bugs.r-project.org/bugzilla/show_bug.cgi?id=17141
The warning emitted from print.factor() is interesting. I'm not sure
why we are setting the class to NULL there. Could just create a new
character vector instead. Will l

The coercion is probably the most viable workaround for now, as it's
consistent with what happens internally for calls. All pairlists/calls
are converted to list for subassignment, but only calls are converted
back. My guess is that the intent was for users to move from using a
pairlist to the "new
Hi Henrik,
It would help to understand your use case for pairlists.
Thanks,

Is there really a need for these complications? Packages emitting this
warning are broken by definition and should be fixed. Perhaps we could
"flip the switch" in a test environment and see how much havoc is wreaked
and whether authors are sufficiently responsive?

I'm curious as to precisely why someone would want to do this.

I guess this would establish a separate "namespace" of symbolic prefix
operators, %*% being an example in the infix case. So you could have stuff
like %?%, but for non-symbolic (spelled out stuff like %foo%), it's hard to
see the advantage vs. foo(x).
Those examples you mention should probably be
Interesting idea. Lazy and non-standard evaluation is going to happen; the
language needs a way to contain it.
I'll extend the proposal so that prefixing a formal argument with @ in
function() marks the argument as auto-quoting, so it arrives as a language
object without use of substitute(). Kind
if I have any of that confused or there are better approaches. I
