Assigning genes to CBS segmented output:
Hi All,
I have an CBS segmentation algorithm output for 10 tumor samples each from 2
different tumors.
Now, I am in an urgent need to assign gene (followed by all genes present)
that belong to a particular segment after I removed all the CNVs from
segment data. The format of the data is:
Sample Chromosome Start End Num_Probes Segment_Mean

comparing two tables
Hi everybody,
I would like to know whether it is possible to compare to tables for certain
parameters.
I have these two tables:
gene table
name chr start end str accession Length
gen1 4 646752 646838 + MI0005806 86
gen12 2L 243035 243141 - MI0005821 106
gen3 2L 159838 159928 + MI0005813 90

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

Resize Graphics Window
Need way to resize an existing graphics window.
This should be applicable across platforms (as part of a package).
Context: function1() draws main plot (I'm using grid), function2() adds smaller plot
above main plot, but this one can sometimes overflow the original graphics window
area.
Thanks,

Facing problem in installing the package named "methyAnalysis"
Dear Sir,
I have been using R for a long time. But recently I have faced a problem
when installing the Bioconductor package named "methyAnalysis". Firstly it
was require to update my older R (R version 3.4.3 (2017-11-30)) in to newer
version. That time I have also updated the RStudio software.
After that when I have tried to install the package named "methyAnalysis".

DESCRIPTION file and Rd examples
I have a confusing error from R CMD check that I don't get when running the example manually by hand.
In the \examples section of an Rd file, I create a GRanges object, then I call a function with the GRanges object, whose first 2 lines are
require(GenomicRanges)
annoDF <- as.data.frame(anno) # anno is the GRanges object.
and that second line gives:

Dear Pijush
You might do better to ask on the Bioconductor list as IRanges does not
seem to be on CRAN so I deduce it is a Bioconductor package too.

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

warning for inefficiently compressed datasets
Hi,
Recently added to doc/NEWS.Rd:
'R CMD check' now gives a warning rather than a note if it finds
inefficiently compressed datasets. With 'bzip2' and 'xz' compression
having been available since R 2.10.0, there is no excuse for not
using them.
Why isn't a note enough for this?
Generally speaking, warnings are for things that are dangerous,

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!!!

Loops for repetitive task
Hello,
I have an R script that I use as a template to perform a task for multiple
files (in this case, multiple chromosomes).
What I would like to do is to utilize a simple loop to parse through each
chromosome number so that I don't have to type the same code over and over
again in the R console.
I've tried using:
for(i in 1:22){
etc..
}
and replacing each chromosome number with
