Hi, I have downloaded around 60GB package repositories of bioconductor to use it locally and to set up mirror at my university site. I have installed the mirror with rsync command and able to access also. Now I have to set a cron job for its daily updating from bioconductor website. How should I do it? I know rsync have to be used but I don't know the proper syntax. I request to send

Hi, I have 15 CEL files of Affymetrix platform from GEO. Title of experiment is : Ecoli_ASv2 Affymetrix E. coli Antisense Genome Array. I am looking for the package available in R for this array for annotation. I have already tried doing annotation from packages like org.EcK12.eg.db but I don't got the success. Is any other package in the form of database available for E.coli for

Hello Everyone, I am writing programs in R from 7 months and I am able to solve most of the errors/issues except for this current post. My Task is to read a Microsoft Excel file(textE_to_affy.csv) which contains the Microarray Expression Values collected from the Illumina Microarray experiment. These collected intensity values need to be normalized(Rank Invariant Normalization) by using the R

Hi, Reading help("Documentation"), I'm led to believe that a help call like: ?myFun(x, sqrt(wt)) Will search for help on the appropriate method in the case that myFun is generic. This isn't working for me. Here is an example using the Biobase package: ## If Biobase is not installed source("http://bioconductor.org/biocLite.R") biocLite("Biobase")

Dear R-helpers & bioconductor Sorry for cross-posting, this concerns R-programming stuff applied on Bioconductor context. Also sorry for this long message, I try to be complete in my request. I am trying to write a subset method for a specific class (ExpressionSet from Bioconductor) allowing selection more flexible than "[" method . The schema I am thinking for is the following:

Hi, I want to change .RDA file to a text file. So I did as follows. >load("my.rda") >ls() ---> then it showed [1] exprs >write.table(exprs,"C:\\my.txt",sep="\t") I was successful with the first .RDA file. Then I used the same commands with another .RDA file (172 MB)which is 4 times bigger than the first file (41.2 MB). When I put the last command

Hey. So I am completely new to WineHQ. But reading the FAQ for bloodline champions, it said it could probably run using WineHQ. As I said, I have a mac. But I have no idea what package I need, how to configure it for BLC, etc. Can anyone help a major noob? http://www.bloodlinechampions.com/ "On what platforms will Bloodline Champions be released? The game is using the Microsoft XNA

Hi all, What are current methods people use in R to identify mis-spelled column names when selecting columns from a data frame? Alice Johnson recently tackled this issue (see [BioC] posting below). Due to a mis-spelled column name ("FileName" instead of "Filename") which produced no warning, Alice spent a fair amount of time tracking down this bug. With my fumbling fingers

Hi, I have configured my model as follows: class Product < ActiveRecord::Base acts_as_ferret :fields => [:description,:label_description,:label_free,:product_id_supplier,:description_supplier,:supplier_description] belongs_to :supplier def supplier_description return "#{self.supplier.description}" end In the development log I can see the supplier_description

Hi, I'm very confused about R structures and the methods to go with them. I'm using R for microarray analysis with Bioconductors. Suppose without reading the documentations, what's the best way to explore a data structure when you know nothing about it? I am currently using is() / class() to see what the object is. str() / attributes() to probe inside the object, and

Hello All, I need your help. I am analysing affymetrix data and have to select the probe-set that has median expression among all the probe-sets for same gene. This way I want to remove the redundancy by keeping the analysis to single gene entry level. I am fully aware that it is not a nice thing to do but I just have to do it. To do so, I came across 'findLargest' function of

Hello, I am to run this R script but i keep getting this error. > expr<-exprs(golubMerge) Warning message: The exprSet class is deprecated, use ExpressionSet instead I tried to find information on the website but no luck.

Running R2.4.0 on Apple Mac OS X 10.4.8, in Emacs ESS mode, and also R.app. In an attempt to learn a bit more about a particular method (geneNames in package affy) I invoked getMethods("geneNames") which produced geneNames methods, but not the one in affy (output below). I had to know the signature (AffyBatch) in order to find the method > getMethod("geneNames",

Hey, I have code that can check the quality of a data set we're working with (expression data), and I'm having some trouble writing code that would make the expression data we have tie to other data we want to link it to (called phenotype data). Does anyone have any advice on how I could make a single object that would do this? Other relevant info: I want to use the pdata() function,

Hi, I started this post on bioc-devel but this seems to be more general: https://stat.ethz.ch/pipermail/bioc-devel/2013-May/004311.html See reproducible example from Martin below. Thank you.

I would like to use lattice graphics to plot multiple functions (or groups or subpopulations) on the same plot region, using different line types "lty" or colors "col" to distinguish the functions (or groups). In traditional graphics, this seems straightforward: First plot all the data using 'type="n"', and subsequently execute a series of "points"

Hi, I am having troubles with creating an eSet and would appreciate any help on the following problem. I am trying to create an eSet using the following code pd <- read.table(file="pdata.txt",header =TRUE,row.names=1); colnames(pd) <- c("type","tumor","time","id"); pdN <- list(type =

I have a data set similar to the set below where 1 and 2 indicate test results and 0 indicates time points in between where there are no test results. I would like to allocate the time points leading up to a test result with the value of the test result. What I have: What I want: 1 1 0 1 0 1 0 1 1
