Detecting Body Onload
I have a piece of code that "waits" for body onload. Every 30ms, it tests
$(''body'').
Seems that isn''t always good enough. I''ve hit situations where the DOM is
"partially" loaded somehow.
I fixed matters by setting a global flag...
<body onload="bodyLoaded=true;">

Class not found when search in .onLoad
Hi,
I am facing with a strange behaviour of isClass and extends when these
are called in .onLoad in both R 2.12.1 and R 2.13.0. This is preventing
my package from doing some object initializations at a proper place
(i.e. in .onLoad).
Suppose one defines two S4 classes in a package, and that one needs to
check the inheritance between these two when loading the package (e.g.
to validate slo...

Prototype Ajax.Request (onLoading and onSuccess) question
...r via Ajax.Request when the
previous (''? <http://luther.edu/new/?cur_month=2005-09>'') or next (''?
<http://luther.edu/new/?cur_month=2005-11>'') month links are clicked .

It seems to work fine if I don''t call anything onLoading.
http://luther.edu/new/noonloading.php
When I do call something onLoading, sometimes it gets stuck and never
makes it to the function I call onSuccess. Any idea what I am doing
wrong? Could I be running up against a race condition? I guess I am
assuming that onLoading will always be cal...

"onload" event handler inside a div
Hi. I need help on what is essentially putting an "onload" event handler
into a div. I am using render :partial and when the partial is loaded, I
would like the divs to show using an effect from a library such as
scriptaculous or moofx. However, there is no "onload" for a div. I was

NAMESPACE, S4, and .onLoad
The Writing R Extensions manual instructs developers who use S4
classes and methods in a package with a name space to:
There needs to be an .onLoad action to ensure that the methods package
is loaded and attached:
.onLoad <- function(lib, pkg) require(methods)
I'm wondering if listing methods in the Depends field of the package's
DESCRIPTION file is sufficient. My understanding is that doing so
will result in the...

Ajax.Request: onLoading executed after onComplete in IE
Hi,
i''m trying to use a visual indicator for my Ajax requests. It''s based on the
shopping cart demo at script.aculo.us and works great in Firefox, Konqueror
and Opera, but fails in IE6. For some reason (timing problems?) onComplete is
executed before onLoading, so the indicator is shown but not hidden when the
request has finished.
Oddly enough it works fine in the shopping card demo. It happens with both,
script.aculo.us 1.5.0 and 1.5.1. Here''s the (somewhat reduced) code i''m
using:

Writing R-extensions
...ge), but the section on `Load hooks' states
Packages with name spaces do not use the @code{.First.lib}
function. Since loading and attaching are distinct operations
when a name space is used, separate hooks are provided for each.
These hook functions are called @code{.onLoad} and
@code{.onAttach}.
I interpreted this as "o.k., loading and attaching are distinct
operations, if I load a package .onLoad (and only .onLoad) is run,
if I attach a package then .onAttach (and only .onAttach) is run".
But the manual continues a bit further down...

Loading namespaces
I'm creating a package for my own use that uses some S4 classes but no
methods.
I have a file called NAMESPACE it contains the line:
exportClasses("foo")
and at the top of the R file I have
setClass("foo", representation(x="numeric")
and the line:
.onLoad<-function(libname,pkgname)
When I run R CMD check I get Syntax error in the only R file. If I comment
out the .onLoad function I get a package/namespace load failed error.
Are libname and pkgname parameters for the function .onLoad that need to
explicitly stated, or does R populate them when...

Best way for rgl's .onLoad to fail?
...default, so I'd like rgl to fail nicely.
Ideally, it will load a library that doesn't need to link to the X11
libs but will still allow WebGL code to work, but that's complicated, so
I'd like a stopgap.
I can detect that the failure is about to happen, and call stop() in the
.onLoad hook, but that gives an ugly message:
> library(rgl)
Error : .onLoad failed in loadNamespace() for 'rgl', details:
call: NULL
error: X11 not found; XQuartz (from www.xquartz.org) is required to
run rgl.
Error: package or namespace load failed for ?rgl?
Alternatively, I can just...

Ajax.Request / XmlHttpRequest details
...HttpRequest''s readyState property can have? I mean, I know what
the states are, but I''m unclear on the circumstances under which each
occurs...
In a simple test I wrote, I''m seeing the loaded, interactive and
complete states (i.e. my Ajax.Request instance calls its onLoaded,
onInteractive and onComplete event handlers). onInteractive gets
called multiple times, so I assume it fires either every so-many-
bytes of response data or every so-many-seconds -- but which is it?
And why isn''t onLoading firing?
The reason I''m asking is, I''m...

How to set options() when a package without a name space is loaded?
...ding a package *without* a name space?
Is it possible?
I though this one was a common question, but I could not find it in
the FAQ, in the help nor in the r-help/r-devel archives. Section
1.6.3 on "Load hooks" in "Writing R Extensions" says that this should
be done using the .onLoad hook, but that does only apply to packages
name spaces, cf. ?.onLoad
