code for double sum
Hi R-users,
I wrote a code to evaluate double sum as follows:
ff2 <- function(bb,eta,z,k)
{ r <- length(z)
for (i in 1:r)
{ sm1 <- sum((z[i]*bb/2)*(psigamma((0:k)+eta+1,deriv=0)/(factorial(0:k)*gamma((0:k)+eta+1))))
sm2 <- sum((besselI(z[i]*bb,eta)*log(z[i]*bb/2) - sm1)/besselI(z[i]*bb,eta))
sm2
}
ff2(bb,eta,z,10)
but it gave me the following m...

Prototype 1.6.0.2 + Firefox 3 Enumerable problems
I am using Prototype 1.6.0.2 on Firefox 3.0b4.
The following does not work when I enter it in Firebug:
$A([1,2,3,4]).each(function(n) {alert(n);});
The above is just an example. Any array, using $A and any enumerable
method, returns the following:
TypeError: iterator.bind is not a function
Seems like some objects are not being extended correctly?

Aggregate with non-scalar function
R-Helpers,
I'm sorry to have to ask this -- I've not used R very much in the last
8 or 10 months, and I've gotten rusty.

Weird Prototype behavior
...ead>
<body>
<input type=''text'' name=''login_username'' id=''login_username_index'' />

IE6 alerts "[object]".
IE7 alerts "[object]".
Opera 9 alerts "[object HTMLInputElement]".
FF2 alerts "null".
If I change the name of the input element from "login_username" to
anything else, all browsers alert "null". Why is the dollar function
reading the name attribute instead of the id? The way I''ve always
understood it, the dollar function ignores...

Firefox and Thunderbird 2.0, Centos 5, and rpms
I am making some progress on my Centos 5 notebook build.
So I am looking at Firefox and Thunderbird 2.0.
Should I install them? Or is Redhat correct that there is nothing
improved here and wait for 3.0? (well I have not even had a chance to
look at Thunderbird 2.0, that is new)?
I have the install steps we covered here back on 2/2/07; but are there
rpms? I did not find anything over at

MLE of negative binomial distribution parameters

FF3 printing problem on Centos 4.x
...long time,
and it tends to work just fine.
yesterday I installed the new FF3 release. It works fine too, with one
exception: The print dialog shows no printers! The print button is greyed
out! There actually four or five printers defined on the system, and all
other apps find them fine, including FF2.
So far no one has replied to my query on the mozillazine forums. Anyone
here got any suggestions I can try?
Thanks!

Odd things happening in ie6/ie7
As always, i am again having problems in IE6 and IE7 with scripts.
The scripting works fine in FF2, opera and Safari. IE just wont load
it. Could anyone help?
It''s a static page for now, located at www.maifith.com/research/index.html
The problem,although quite obvious, is that it doesn''t load the JS in
IE6 or IE7. Any help would be appreciated.

Creating functions with a loop.
Hi
I am trying to create n functions where each function is defined in function one step before, i.e. something like
ff.k(x) = ff.j(x) - sum(1:j), for j=k-1
Is it possible? If it isn't and I manually create each function then is their a way to call them through a loop? My objective is to calculate something like
result.k = ff.k(x1)/ff.k(x2) for k in 2:n
Thank you for your time,

Sound support for script.aculo.us
...alling back on using whatever plugin is used for audio/mpeg on other
browsers (in real world terms, this means QuickTime or a QuickTime-
compatible plugin).
Thanks to Jules Gravinese of http://www.webveteran.com/ for coming up
with the initial idea and code for this.
Tested and works in IE7, FF2, Safari.
You can have a look at this by grabbing the latest SVN trunk, and
summoning the sound_test.html functional test file.
Note that this feature isn''t meant for any heavy-duty music playback,
but just for little sound effects that enhance the user experience.

Keeping factors with zero occurrences in "table" output
Dear R group,
I have a data frame which contains data on preferences on 7 items (ranks 1
through 7) listed by each participant. I would like to tabulate this in a
7x7 table where the rows would be the items and the columns would be the
number of times that item received a particular rank.
I tried doing this by creating a matrix by "rbind"ing each vector obtained

If either Michel or Tom is interested in hosting this, I'll be happy
to do the grunt work for a real integration. It's kind of pain in the

I've tested this in Safari 3.1, FF2/Mac, FF3/Mac, and IE7. Email me
if you have any problems.

Gauss-Laguerre using statmod
I believe this may be more related to analysis than it is to R, per se.
Suppose I have the following function that I wish to integrate:
ff <- function(x) pnorm((x - m)/sigma) * dnorm(x, observed, sigma)
Then, given the parameters:
mu <- 300
sigma <- 50
m <- 250
target <- 200
sigma_i <- 50
I can use the function integrate as:
> integrate(ff, lower= -Inf, upper=target)

[LLVMdev] A weird problem when try to output operand of instruction involving function pointer in a struct
...();
opi!=opie; ++opi){
if (Instruction *Op = dyn_cast<Instruction>(*opi)){
errs() <<Op->getOperand(0)->getName() <<", ";
}else{
errs() <<"noti\n";
}
}
}
}
}
}
The output is:
In function: main
A,
indirect call: tt1,
indirect call: ff2,
indirect call: tt4,
indirect call: ppp,
indirect call: kkk,
You can find that there is a number after tt and ff, I have no idea where
they are coming from. Can anyone give some hint?
Thanks.

Multiple form weirdness in IE6
...is clicked, an alert pops up saying "I am in
button1Func", but then the status bar says it is calling the action
for the first form and not the second. When I move the first form to
the bottom of the page, the first button works correctly. What is
going on here? It seems to work ok in FF2 and IE7.
Thanks,
