Whole genome searching of 100bp "D" sequence
Hi,
I was wondering I'm going about this in the correct way. I need to test if
there are coding sequences or exons in hg19 which match a string of 100bp
"D" i.e. [A,G or T]. However I'm getting a strange result.
I get a hit on chr7, using the 100bp search however when I search with 60bp
sequence of "D" I don't get any hits.

GridR
Dear All
I am doing one distributed data mining program. So I selected GridR
package for the distributed programming.
*grid.init(service="local",debug=FALSE, localTmpDir="GridRTmp/")
grid.apply("x",UCS, wait=TRUE )*
UCS is a function.
When I execute this statement, I have some errors like :
*cannot load local function/variable: xmlRoot
extracted from line: : no

Dispatch method on S3 or S4 class
Hello,
I've been attempting to make a generic method that dispatches on the first argument, which can be either an S3 or an S4 class. This is as far as I've gotten. Any suggestions about what to try next ?

library(GenomicRanges)

Memory Leak
Hello,
I'm trying to track down the cause of some extreme memory usage and I've been using Dirk Eddelbuettel's lsos() function he posted on stack overflow. There is a large difference between R's RAM usage :

Is that an efficient way to find the overlapped , upstream and downstream ranges for a bunch of ranges
I do have a bunch of genes ( nearly ~50000) from the whole genome, which read in genomic ranges
A range(gene) can be seem as an observation has three columns chromosome, start and end, like that
seqnames start end width strand
gene1 chr1 1 5 5 +
gene2 chr1 10 15 6 +
gene3 chr1 12 17 6 +
gene4 chr1 20 25 6 +

nomianl response model
Is there a way to estimate a nominal response model?
To be more specific let's say I want to calibrate:
\pi_{v}(\theta_j)=\frac{e^{\xi_{v}+\lambda_{v}\theta_j}}{\sum_{h=1}^m
e^{\xi_{h}+\lambda_{h}\theta_j}}
Where $\theta_j$ is a the dependent variable and I need to estimate
$\xi_{h}$ and $\lambda_{h}$ for $h \in {1...,m}$.
Thank you,

Combining: R + Condor in 2009 ? (+foreach maybe?)
Hello dear R-help group (and David Smith from REvolution),
I would like to perform parallel computing using R with Condor (hopefully
using foreach or other recommended solutions, if available) for some
"Embarrassingly parallel" problem.
I will start by listing what I found so far, and then go on asking for help.
So far I found the a manual by Xianhong Xie from Rnews_2005-2 (see page

Error during scp transfer
Dear all
I am implement one grid computing system using GridR package. I am
working on windows platform. I did all the configuration according to
the GridR tutorial.
But it has some errors when I execute grid.apply function.
Here is the output from stderr:
R: not found

How to obtain restricted estimates from coxph()?
Hello,
I'm trying to use coxph() function to fit a very simple Cox proportional
hazards regression model (only one covariate) but the parameter space is
restricted to an open set (0, 1). Can I still obtain a valid estimate by
using coxph function in this scenario? If yes, how? Any suggestion would be
greatly appreciated. Thanks!!!

fusion of overlapping intervals
Hello,
I have start and end coordinates from different experiments (DNase
hypersensitivity data) and now I would like to combine overlapping
intervals. For instance (see my test data below) (2) 30-52 and (3) 49-101
are combined to 30-101. But 49-101 and 70-103 would not be combined because
they are on different chromosomes (chr a and chr b).
Does anybody have an idea?
Thanks

Hi everyone,
I'm trying to do an Logistic Politomic Regression in R. Because I have my resposes variables and the aswer is 0 and 1 in 3 bacterial genes. Somebody know how to do this in R in a easy way?
Thank so much,
