Dear R users,
I am using the beadarray package. I am trying to upload raw bead-level data using these commands:

nlme package
In using the NLME package (R 2.6.1 for Windows), I am having a problem in running an R script that used to run with no problems using a Linux OS in 2004. So I am wondering if during these last ~3 yrs we had major changes in the syntax of the NLME package that I am not aware.
This is the R script:
library(nlme)
treat=as.factor(c(1,2,1,2,1,2,1,2))
mouse=as.factor(c(1,1,2,2,3,3,4,4))

This bug occurs when using the (D)COM server to connect to the "expresso"
command of the Bioconductor Affy package. It may be a bug of R, (D)COM or Affy
ut I will report it here anyway as it feels like an R bug.
The Affy package when invoked will read a series of large (10Mb) text files

stuck with affy / limma
Hi,
I have a question concerning the analysis of some affymetrix chips. I
downloaded some of the data from GEO GSE11324 (see below). In doing so I'm
stuck after I identified the probesets with significant changes. I have
problems in assigning probeset specific gene names as well as getting the
genomic coordinates. Furthermore I have no clue how to deal with the fact,
that most genes have

Memory problem ... Again
Happy new year to all;
A few days ago, I posted similar problem. At that time, I found out that our
R program had been 32-bit compiled, not 64-bit compiled. So the R program
has been re-installed in 64-bit and run the same job, reading in 150
Affymetrix U133A v2 CEL files and perform dChip processing. However, the
memory problem happened again. Since the amount of physical memory is 64GB,

Configuration of memory usage
Hi, all;
I know there has been a lot of discussions on memory usage in R.
However, I have some odd situation here. Basically, I have a rare
opportunity to run R in a system with 64GB memory without any limit on
memory usage for any person or process. However, I encountered the memory
problem error message like this:
Error: cannot allocate vector of size 594075 Kb

topTable function from LIMMA
Dear R-Help,
I am using the function "topTable" from the LIMMA package. To estimate
adjusted P-values there are several options (adjust="fdr" , adjust="BH")
as shown below:
topTable(fit, number = 10, adjust = "BH", fit$Name)
I guess any of these options (fdr, BH, etc.) is using a default of
FDR=0.05 which is quite conservative (i.e., very

How to cite the the PDF user's guide for LIMMA
Dear All,
How to cite the PDF user's guide for the LIMMA package?
This is not about how to cite the LIMMA package.

Ordering of rows/names
Hi all,
I have a data.frame e3. I use a function on it:
n3 <- normalize.qspline(x = e3, samples = 0.07, na.rm = TRUE);
The resulting data.frame has lost it's row-names and column names. This
is the natural behaviour of the function I am calling, and I can't alter
that at the moment. However, the data *is* in the correct order, as it
was initially -- the names are just missing in

ext3 and df don't agree ?
I've taken my RH7.1 system, rebuild kernel (2.4.9 with ext3 patches) and
followed the ext3 instructions to install.
Everything seems to work OK but -
df -k
doesn't list the ext3 partition (my root partition).
Is this a known problem ?
If not, how best can I gather diagnostics to identify the source of the
problem ?
Thanks
