Dear folks, Please welcome a newbie both to R and the mailing list :). I am currently working on a sequencing project, and heard about R as well as some of its packages for next gen sequencing, and decided to give it a try. Starting with ShortRead, I found a document (http://www.bioconductor.org/packages/2.5/bioc/vignettes/ShortRead/inst/doc/ShortRead_and_HilbertVis.pdf) which does mention

Dear R-Help, I would be most grateful if you could inspect the attached install file. I would like to be able to use ShortRead to generate QA reports for Genome Analyzer output data. OS: Linux CentOS 5.3 on HP Proliant server . In process of installing "R" package after configuration flagging some missing modules-libraries the install process will not perform 'make' function.

In pvec(list(1, 2), FUN, mc.cores=2) FUN sees integer() arguments whereas pvec(list(1, 2, 3), FUN, mc.cores=2) FUN sees list() arguments; the latter seems consistent with pvec's description. This came up in a complicated Bioconductor thread about generics and parallel evaluation https://stat.ethz.ch/pipermail/bioc-devel/2012-October/003745.html One relevant point is that a

Hi, I want to group a large list (20 million) of strings into categories based on string similarity? The specific problem is: given a list of DNA sequence as below ACTCCCGCCGTTCGCGCGCAGCATGATCCTG ACTCCCGCCGTTCGCGCGCNNNNNNNNNNNN CAGGATCATGCTGCGCGCGAACGGCGGGAGT CAGGATCATGCTGCGCGCGAANNNNNNNNNN CAGGATCATGCTGCGCGCGNNNNNNNNNNNN ...... .....

Hello all, I upgraded my R workstation, and to my dismay, only one core appears to be used during intensive computation of a bioconductor function. What I have now is two dual-core Xeon 5160 CPUs and 10 GB RAM. When I fully load it, top reports about 25% user, 75% idle and 0.98 short-term load. The archives gave nothing helpful besides mention of snow. I thought of posting to HPC, but this system

Hello everyone. There is a new competition, outlined on the blog dataists<http://www.dataists.com/2010/10/using-data-tools-to-find-data-tools-the-yo-dawg-of-data-hacking/>, inviting us to analyse statistics of the use of R packages (collected from 52 R users), to create a R-package suggestion engine for ourselves. Since I noticed several bloggers already wrote about it (as I have detailed

I have a two part question Part 1) I am trying to remove characters in a string based on the position of a key character in another string.? I have a solution that works but it requires a for-loop.? A vectorized way of doing this has alluded me.? CleanRead<-function(x,y) { ? if (!is.character(x)) ??? x <- as.character(x) ? if (!is.character(y)) ??? y <- as.character(y) ?

Based on some testing it seems to me that if I have a package with a dataset in /data a Sweave vignette in inst/doc (but no associated pdf file) the vignette loads the data in /data through data(dataset) and I do a R CMD build R will try to build the pdf version of the vignette, but will be unable to find the dataset in data because the package is not yet installed. However, if I do

Hi, I am bring SPEEX up on Analog Device's Blackfin (using Visual DSP++ tool set). The floating point was too slow on this fixed-point processor so I am going for the integer version. The floating point library build was very clean, but when I build with FIXED_POINT defined, the compiler exits when it find this discrepancy in \libspeex\cb_search.c : ".\libspeex\cb_search.c",

Hi All I am experimenting with a system comprising Cisco UCS Blades and Nexus 5k switches. I am trying to understand the best way to define network interfaces for my vms, without having to specify exact source device names or PCI addresses, as I want to be able to migrate vms between nodes and not have to worry about namespace or pcispace collisions. At the moment my network definition looks
