Determinant and inverse using cholsky parameter
Dear R list members,
I have a vector of Cholesky parameterization of a matrix let say A. I would like to compute the determinant and inverse of the original matrix A from the vector of cholesky parameters , would you suggest an R function to do the task. I have tried hard but unable to find anything like that.
Please direct me any package or please share R code that can do the task.
Thanks and

mle (stat4) crashing due to singular Hessian in covariance matrix calculation
Hi, R developers.
when running mle inside a loop I found a nasty behavior. From time to
time, my model had a degenerate minimum and the loop just crashed. I
tracked it down to "vcov <- if (length(coef)) solve(oout$hessian)" line,
being the hessian singular.
Note that the minimum reached was good, it just did not make sense to
calculate the covariance matrix as the inverse of a

[LLVMdev] VMKIT problem
Hi Nicolas,
I'm running it on Kubuntu.
Now that you mention it I did have a problem during vmkit setup. After
running the ./configure file with all the options I ran the make file it was
giving this error:
make[3]: ***
[/.automount/root/exports/transient/nataraj/Project/vmkit-0.25/lib/Mvm/Runtime/Release/EscapeAnalysis.o]
Error 1

So I went into Makefile.common and modified GNU

[LLVMdev] VMKIT problem
Thanks Nicolas, Gaël
I followed your instructions and installed compatible versions of llvm,
vmkit and GNU Classpath also I unzipped glibj.zip and pointed GNU Classpath
lib variable to the the unzipped files during vmkit configure. That error
has vanished.
Now when I run jnjvm or vmkit in Release/bin on any file I'm getting a new
error :

[LLVMdev] VMKIT problem
Yes I did, one thing worth mentioning is on running configure for GNU
Classpath towards the end
this error is displayed and it crashes, I assumed it was okay and went to
create the symbolic links and
completed the rest of the process with vmkit mentioned in Getting Started as
instructed:
-I../../../native/jni/native-lib -W -Wall -Wmissing-declarations
-Wwrite-strings -Wmissing-prototypes

[LLVMdev] VMKIT problem
Hi Nataraj,
You're using incompatible versions of vmkit and GNU Classpath. First,
you should use vmkit 0.26 and llvm 2.6 (at least, -- use trunk if there
are problems). Second, you should use GNU Classpath 0.97.2.
Good luck!

Hi Nataraj,
Which platform are you running on? Did you follow all the steps on
vmkit.llvm.org getting started page, especially for GNU Classpath?
Thanks!

Bootstrapping a covariance matrix
Dear all I am a bit new to R so please keep your swords sheathed!
I would simply like to bootstrap a covariance matrix from a multivariate
gaussian density. At face value that seemed like a very straightforward
problem to solve but I somehow could not get the boot package to work and
did not really understand the documentation so I tried to do the bootstrap
manually. Hence:

confusion over S3/S4 importing
Can anyone help me figure out the right way to import a method that is
defined as S3 in one package and S4 in another?
Specifically:
profile() is defined as an S3 method in the stats package:
function (fitted, ...)
UseMethod("profile")
<bytecode: 0xa4cd6e8>
<environment: namespace:stats>
In stats4 it is defined as an S4 method:

S3 and S4 clash
Hello:
How can I work around the conflict between the S3 and S4
illustrated in the example below? I'm developing a package that
requires a function in 'stats4', but when 'stats4' is attached, it
breaks my AIC function. I could give my AIC function another name so it
no longer uses the generic dispatch, but I wonder if there is another way.
Thanks,

I have a web application which uses sudo to invoke python scripts as the

reason why sudo would would require sys_ptrace access for this?? I only
get this violation intermittenly, and not with every call to sudo.?
