Ordering a matrix based on cluster no
Hi All
I have a symmetric matrix of genes ( 100x100 matrix). I also have a matrix
(100x2) of two columns where column 1 has the gene names and column 2 has
the cluster it belongs to (they are sorted and grouped based on the cluster
no).
I would like to order the rows and columns of the 100x 100 matrix such that
the first n genes correspond to cluster 1 and next n genes correspond to
cluster 2

substituting own test statistics in a built-in function
Hi All
I would like to compute the raw p-value from permutation tests and I found
mt.sample.rawp() from the package multtest almost similar to what I want to
do. But in the function definition:
mt.sample.rawp(V,classlabel,test="t",side="abs",fixed.seed.sampling="y",B=10000,na=.mt.naNUM,nonpara="n")
I would like to choose my own t-test which is designed

How to create a numeric data.frame
Hi All
I am new to R and I am not sure of how this should be done. I have a matrix of
985x100 values and the class is data.frame.
A sample of my dataset looks like this (Since its a huge dataset and it would
make the screen look more complex, I am pasting only the first few rows and
columns.

User directories in /home are missing
Hi,
I use Redhat Enterprise Edition 2.4.21 kernel version. In my system all
the user directories in /home disappeared. No one deleted it. But I
don't know how it is missing. I had one or two open sessions where I
already logged in as root and cd'ed to one particular home directory.

URGENT: How to recover ext3 files?
Hi,
After panic boot, I have executed fsck for the mount point and we
couldn't find a single file. We have lot of directories under lost+found
like this #3194985.
Can anyone tell me how to recover the data from this folder? This is
urgent.
Thanks in advance for your help.

Create simulated data's using mvrnorm
Hi All
This might be something very trivial but I seem to miss something in the
syntax or logic which makes me keep wandering around the problem without
arriving at a solution.
What I want to do is to simulate a sample data for performing cluster
analysis. I tried to use
x1= mvrnorm(10,rep(0.8,3),diag(3))
x2= mvrnorm(10,rep(0,3),diag(3))
x3= mvrnorm(10,rep(-0.5,3),diag(3))
x=rbind(x1,x2,x3)

Help needed to recover data from ext3 file system where mkfs was issued accidentally
Hi,
I connected my harddisk which had ext3 filesystem and some files
archived in it as slave device and issued "mkfs /dev/hdb2" accidentally.
Immediately I issued Ctrl C and stopped the process. But before that it
had deleted some 100 Blocks.
After that I am unable to boot that hard disk as primary device. The
system is asking me "please insert a valid boot device and press

passwd : Module is unknown (Redhat 9 Enterprise Edition)
Hi All,
Can anyone help me in resolving this problem.
I use Redhat 9 Enterprise edition. I have a session in which I logged in
as a root. When I issue the command "su" from any other user it is
throwing error "su : Incorrect password", If I try to change the
password from the root session, it is throwing error "passwd : module
unknown".

Fitting linear models
I am not sure if this is an R-users question, but since most of you here
are statisticians, I decided to give it a shot.
I am using the lm() function in R to fit a dependent variable to a set
of 3 to 5 independent variables. For this, I used the following
commands:
>model1<-lm(function=PBW~SO4+NO3+NH4)
Coefficients:
(Intercept) SO4 NO3 NH4

I was also wondering what will the llvm IR be for pthreads ?

[LLVMdev] decimal to floating point conversion
Hi all:
I need an instruction that can convert decimal values into floating point
numbers.
i.e. say I have a decimal number 1110794174 (== 42355FBE in hex ) and (==
45.3435 as a float)
essentially the mantissa and exponent representation needs to be used.
Is there any way of doing this in llvm?
Thanks and Regards

[LLVMdev] multithreaded applications
Hi all:
I am working on a project using llvm and we need to deal with multithreaded
applications. I wanted to know if there was a C front end for llvm that
could parse multithreaded applications? I tried llvm-gcc (4.2) and could not
get it to work. Is there an extra parameter that I need to pass or something
?
Thanks a lot for your help.

[LLVMdev] generation of shared libraries.
Thanks a lot.
A see the shared library in linux version. I initially tried doing this in
cygwin where I dont see the shared library being built. Do u think it could
have been cygwin that is the problem?

[LLVMdev] generation of shared libraries.
I am trying to run the LLVM hello world pass. I observe that in the
OUPUT_DIR/lib the LLVMHello.a and LLVMHello.la libraries are generated. But
I am confused as to how to generate the .so library file from here.
I am kinda new to compilers and hence the question I know is basic , but
couldnt figure the answer out myself.
Thanks a lot for your help.

Okay. Luke gave hints on how to get pthreads to work. LLVM doesn't do
anything special for pthreads calls. So they should look like regular
calls into a library.

[LLVMdev] Pass Ordering
All,
I have a ModulePass (A) calling a FunctionPass that inturn calls TargetData
(a ModulePass). For reasons of code correctness and modularity I cannot
reorganize my passes in any other way .
When I use opt to load and run A , it gives the following error.
LLVM ERROR: Bad TargetData ctor used. Tool did not specify a TargetData to
use?

[LLVMdev] AESOP autoparallelizing compiler
Hi Sebastian,
Sure! The bulk of LMDA was written by Aparna Kotha (CCd). It computes dependences between all instructions, computes the resulting direction vectors in the function, then associates them all with loops.
At a high level, the dependence analysis consults with AliasAnalysis, and ScalarEvolution before resorting to attempting to understand the effective affine expressions and

Controlling widths in write.fwf()
Is there a way to handle the widths of values being written to a file
using wrtite.fwf() ?
For example, I used read.fwf(file, width.vector) to read a file. After
making the necessary data manipulation, I want to write the data to a
new file in the same width.vector format. Is there a way to specify
this?
Thanks in Advance

[LLVMdev] Pass Ordering
I am using opt , so i cm confused if i need to do this. On the other hand I
modified my functionPass not to call TargetData , and I still get this

[LLVMdev] generation of shared libraries.
I believe because cygwin behaves like windows (it is just a posix
layer over window) it doesn't have dynamic linking hence only static
libraries have been built.
