can a class find out it''s instance name?
Hi friends - a javascript question....
Does the prototype object add some way for a class to find out the
variable name of its instance variable?
Or does javascript have some built in way to do this?
This is confusing to describe - but if I define a variable as some
object:
var myVariable= new Widget(''fdfa'');
can some built-in method inside the Widget class be

Reading through a group of .RData files
Hi.
I have a procedure that reads a directory, loops through a set of particular .RData files, loading each one, and feeding its object(s) into a function, as follows:
cvListFiles<-list.files(fnDir);
for(i in grep(paste("^",pfnStub,".*\\.RData$",sep=""),cvListFiles)){
load(paste(fnDir,cvListFiles[i],sep="/"));
myFunction(rliObject);
rm(rliObject);
};

sys.call() inside replacement functions incorrectly returns *tmp*
Kia Ora
> Although I'm not sure what problem it would solve...
Given that you asked, I was interested in writing a multiple assignment
function as a replacement function, so something like:
massign (x, y, z) = construct.some list ()
Obviously, that's not possible.
Probably the best example I can think of is converting cartesian
coordinates to polar coordinates.
Then we might have

Autocomplete and Firefox
Having problems with the autocomplete on my linux box and firefox.
When I use form tags it breaks, without form tags everything works fine.
Exact copy of the example provided, but I added form tags.. The initial
search and select works but then the box sort of "locks up" and I can''t
change it at all, If I do try to type something nothing changes but a

How to call a javascript function from rails view?
Is there a way to call a javascript function from within a rails view?
I can''t use the onLoad javascript method inside the <body> tag because I
don''t have control over the body tag, it''s in my header.
There are several rss feed reading functions that are in the page and I
would like to call those functions while the page is being loaded or

"registering" a generic method for a class
Sorry in advance if this is too simple a question, but I'm stuck with
some odd behavior and I can't find the text to rid myself of this
(admittedly somewhat trivial) problem. Note that I've done generic
programming with S3 "objects" in the past, but I've never really
dabbled in creating S4 objects until now.
So, I've created a new S4 class, call it

Dots argument in apply method
Hello everyone,
I'm working on a package using S4 classes and methods and I ran into the
following "problem" when I tried to create an "apply" method for objects
of one of my new classes. I've found a way around the problem but I
wonder if I did not paint myself into the corner. I'd like your opinion
about that.
So I have an object "myObj" of class

Underscores in package names
Martin,
Thank you for discussing this amongst R-core and for detailing the
R-core discussion here.
Some specific examples where having underscores available would have
been useful.
1. My primerTree package (2013) was originally primer_tree, but I had
to change the name to camelCase to comply with the check requirements.
Using camelCase in the package name makes reading code jarring, as the

Discrepancy between is.list() and is(x, "list")
> the prison made by ancient design choices
That prison of ancient design choices isn't so bad.
I have no further comments on object oriented semantics.
However, I'm planning to follow the following design pattern.
If I set the class of an object, I will append the new class to the
existing class.
#good
class (object) = c ("something", class (object) )
#bad
class (object)

I know I said that I had no further comments on object oriented semantics.
However, I found a contradiction in the R documentation.

bugs in head() and tail()
(Using R 3.5.3).
I found bugs in head() and tail().
The following works:

However, the following does not:

Format printing inside a matrix
Hi everyone,
I am not sure if there is an existing solution to this, but I want my S4
objects inside a list matrix showing correctly. Currently it shows as:

..@ ptr:<externalptr>
R> matrix(lst, 2)

probably a simple enough solution but don;t seem to be able to get my head around it...example based on a publicly available data set:

generic onDragStart onDrag and onDragFinish events extracted from scriptaculous?
Hi folks.
I''m working on a project where I need some drag and drop, but I need to
implement what happens in a very different way, so I''m creating my own class
for it. I don''t want to reinvent the wheel and redo Thomas'' excellent
drag/drop functionality, nor do I want to copy/paste his code over into mine.
So, I was wondering, has anyone tried to extract

how do i retrieve a newly created id
in my code i''m calling save on an object. The id gets created as the object
is persisted. How can i retrieve that newly created id? I guess I could
query the table again using the other attributes of the object but is there
another way?
thanks in advance.

Wishlist: Make screeplot() a generic (PR#9541)
Full_Name: Gavin Simpson
Version: 2.5.0
OS: Linux (FC5)
Submission from: (NULL) (128.40.33.76)
Screeplots are a common plot-type used to interpret the results of various
ordination methods and other techniques. A number of packages include ordination
techniques not included in a standard R installation. screeplot() works for
princomp and prcomp objects, but not for these other techniques as it
