Conditional Distribution of MVN variates
Hi Folks,
Given k RVs with MVN distribution N(mu,S) (S a kxk covariance matrix),
let (w.l.o.g.) X1 denote the first r of them, and X2 the last (k-r).
Likewise, let mu1 and mu2 denote their respective expectations.
Then, of course, the expectation of X2 given X1=x1 is
mu2 + S21*inv(S22)*(x1 - mu1)
and the covariance matrix of X2 given X1=x2 is
S22 - S21*inv(X11)*S12
where Sij is the

Reading data in lisp format

I am trying to read the "credit.lisp" file of the Japanese credit database in UCI repository, but it is in lisp format which I do not know how to read. I have not found how to do that in the foreign library

Wide to long form conversion
I have some data 'myData' in wide form (attached at the end), and
would like to convert it to long form. I wish to have five variables
in the result:
1) Subj: factor
2) Group: between-subjects factor (2 levels: s / w)
3) Reference: within-subject factor (2 levels: Me / She)
4) F: within-subject factor (2 levels: F1 / F2)

Lattice: combine the same strip?
Hello R helpers,
I am producing a figure with dual strips, i.e., x~y | S1 + S2, where S1 and
S2 are two strips. For example, in figure 2.1 at
http://lmdvr.r-forge.r-project.org/figures/figures.html.
In this case, I would like to combine the the top strip, since all three
pictures in the same row have the same level based on the first strip. In
other words, instead of

[ARM] Register pressure with -mthumb forces register reload before each call
If I'm understanding what's going on in this test correctly, what's happening is:
* ARMTargetLowering::LowerCall prefers indirect calls when a function is called at least 3 times in minsize
* In thumb 1 (without -fno-omit-frame-pointer) we have effectively only 3 callee-saved registers (r4-r6)
* The function has three arguments, so those three plus the register we need to hold the

[LLVMdev] Request for merge: GHC/ARM calling convention.
Hi Karel,
I understand this patch has already been merged (to 3.0), so don't
take my question as stopping the merge to head, I'm just making sure I
got it right... The rest looks correct.

[LLVMdev] Request for merge: GHC/ARM calling convention.
Hello,
first of all: one of the LLVM 3.0 new feature was a support for GHC
specific calling convention on ARM platform. It looks like this support
was merged just into 3.0 branch, specifically it appeared in 3.0 RC2.
Anyway, I hope this is just a mistake or omission that such support was
merged only into 3.0 and not also into HEAD. I've just found it by
testing LLVM 3.1 with GHC 7.4.2 and

Multivariate regression method
Hi Folks,
Thanks to several people's suggestions and clarifications,
I think I have implemented a function which computes the
conditional mean and covariance matrix of a subset of the
dimensions of an MV-normal variable, given the values on the
other dimensions (these conditioning value can be presented
as a matrix, to deal with several cases at once).
The code is below, for anyone who would

Multiple hist(ograms) - One plot
Hello,
I am trying to plot multiple histograms with the same scales, etc into one
plot. The commands below produce a 3 page PDF with each histogram occupying
the upper right quadrant. And use slightly different scales on the X and Y
axes.

Boxplot in order
Hi,
I need construct box plot graph, but I want keep Groups
order
karla = data.frame(
Groups =
factor(rep(c('CPre','SPre','C7','S7','C14','S14','C21','S21'),
11)),
Time = rep(c(0,7,14,21), 11),
Resp = valor
)
boxplot(Resp~Groups, order=T)
doesn't work.
How do this?

[ARM] Register pressure with -mthumb forces register reload before each call
Hi,
I have attached WIP patch for adding foldMemoryOperand to Thumb1InstrInfo.
For the following case:
void f(int x, int y, int z)
{
void bar(int, int, int);
bar(x, y, z);
bar(x, z, y);
bar(y, x, z);
bar(y, y, x);
}
it calls foldMemoryOperand twice, and thus converts two calls from blx to bl.
callMI->dump() shows the function name "bar" correctly, however in

Printing output together
Hi!
I want to print the output all together with a single column name

n<-length(ns);
Mn<-mean(ns)
Sn2<-var(ns)
return(cbind(x,Mn,Sn2));

non-standard boot floppys
I experimented with floppy sizes. Eg. I used FDFORMAT v1.8 to format a Disk

save space, but I'm not using that.)
All the information is written nicely to the Boot-Record

finite mixture modeling
Hi all,
I have a question, is there any R package dealing with latent transition analysis with both categorical and continuous indicators? So far what I found from GOOGLE are only packages dealing with latent class analysis. So what about the longitudinal situation? Any way we could look at the transition from one class to another across time points?
Thank you very much.

posterior probability in finite mixture
Dear All,
This is a question somewhat off-topic.
Say, if I have known the number of components in the mixture, all the
estimated parameters, prior probabilities, and so on for a finite
mixture model, how might I compute the posterior probabilities of each
case for a new dataset without observed response (Y)? I want to know
the parametric form of such calculation such that I can calculate it

FW: Best R package for Finite Mixture Models or Latent Class Models
Can anyone point me to a comparision of the various packages avaliable to do Finite Mixture Models or Latent Class Models in R. As ever my googling only produce papers on specific packages or implementations. I am looking of a considered comparision that criticlaly compares them. Failing that just your own opinion or experience would be nice to hear.

clustering with finite mixture model
Dear R-help,
I am doing clustering via finite mixture model. Please suggest some packages in
R to find clusters via finite mixture model with continuous variables. And
also I wish to verify the distributional properties of the mixture distributions
by fitting the model with lognormal, gamma, exponentials etc,.
Thanks in advance,
