Dear Sirs, How can I revert to an older limma version? Typing "install.packages("limma")" in R gives a list of mirrors. How can I install the version I want after I obtain and untar the file (e.g, limma_2.9.1.tar.gz)? I am running R 2.5.0 on a Linux machine (CentOS 5). When using limma it will not go past the read.maimages command. I get this error: Error in

Dear mailing group, This is my first time here. Glad to have this resource! I am currently trying to load an Excel file into R (limma package loaded) using the source(*name of directory*) command, but it cannot open the file. I renamed the file as .R and .RData, to no avail. The Excel data contains one gene name per row and about 100 data points per gene (columns). I am only used to

The inst/doc directory of the DAAG package has 6 files coral551.spot, ... that are around 0.85 MB each. It would be useful to be able to zip then, but that as matters stand interferes with the use of the Sweave file that uses them to demonstrate input of expression array data that is in the "spot" format. They do not automatically get unzipped when required. I have checked that

Hi, I am following the protocol outlined here for analysis of single channel Agilent microarray data: http://matticklab.com/index.php?title=Single_channel_analysis_of_Agilent_microarray_data_with_Limma I keep getting the following error message when using Limma's read.maimages function to load my data into an RGList object: Error in RG[[a]][, i] <- obj[, columns[[a]]] : number of

Hi Everyone, I have been trying to read some Arrayvision files( 2 channel cDNA) and am having some problem. My code is : setwd('C:/work/data/limma/ndd1'); files <- c('ndd1_1.txt','ndd1_2.txt','ndd1_3.txt'); RG=read.maimages(files,"arrayvision",sep="\t"); #Normalisation MA=normalizeWithinArrays(RG); #plotPrintTipLoess(MA); #Fit Linear

Dear all, Trying to produce 4 maImage plots (marray package) on the same device (2 on the top and 2 on the bottom) with the layout() function or the split.screen() function, we are facing the following problem: it seems that maImage() does nt care about any of these 2 functions, and plots only one image at a time. Maybe this is inherent to this maImage() function, but we did not find anything

Hi, everyone, I ran the test case in "Introduction to the Bioconductor marrayInput package first. When I ran the session in (read.marrayRaw) I got the following error messages. Other sessions work well. The functions and errors are labled with blue and red respectively. >mraw <- read.Spot(path = datadir, layout = galinfo$layout, gnames = galinfo$gnames, target = swirlTargets) Error

Hi, I'm working with custom slides(Cy5) and working in the normalization of the arrays. I have three arrays (technical replicates). I have sucesfully normalized the data using vsn, however i would like to normalize using spike in controls. My controls are annotated as CTL-1 to x and i would like to do etiher a normalization by block per array or the mean of all the controls per array. The gal

Dear list members, I am analysing my microarray data using limma package. Now I encounter several problems. Looking forward to your suggestions! Question 1: During the process of background correction using method="normexp", four warning messages appeared as "NaNs produced in: log(x)" (as you can see in the program posted below). What does that mean? How will it effect the
