DNAcopy package output data
Hello R Developers
I am using DNACopy package
http://bioconductor.org/packages/1.9/bioc/html/DNAcopy.html
I am not able to figure out how to (if at all possible) to modify
output format, namely, I am getting the following:
"ID" "chrom" "loc.start" "loc.end" "num.mark" "seg.mean"
Is it a way to get also median and standard deviation?

Exporting objects plotted with plot3d() - rgl package
Dear all,
Can anybody tell me how to export a 3d figure made with the plot3d
function? I'm careless about whether it's still interactive or not in
another format, as long I can get it out of R.
Thanks!

how to increase the limit for max.print in R
Hi All,
I am using DNAcopy package in R for copy number analysis of 500K chip.
The final output which I get from DNA copy is too big to be printed in a
file.
So I am getting an error as "reached getOption("max.print") -- omitted
475569 rows "
Can somebody please provide me the pointers with how to increase the limit
for max.print .
Thanks,
Pooja

Suggests and examples
I apologize in advance for probably missing something obvious, but if
someone could point me in the right direction I'd be grateful. This
NOTE is not unique to our package (I list a few others, below).
Package bcp has several Suggests (strucchange, for example).
Then in an Rd file, we have
if (require(strucchange)) {
# Doing some examples making use of strucchange

write.table (PR#1219)
Full_Name: Adam B. Olshen
Version: 1.3.1
OS: Linux
Submission from: (NULL) (140.163.222.233)
There appears to be a bug with write.table if the object being written is a
matrix.
Specifically, the option row.names=F gives an error. I have seen this problem
repeated in the Windows implementation. An example is below.

"could not find function" after import
I am trying to build a package (GWASTools, submitted to Bioconductor)
that uses the "sandwich" package. I have references to "sandwich" in
DESCRIPTION:
Imports: methods, DBI, RSQLite, sandwich, survival, DNAcopy
and NAMESPACE:

In the code itself is a call to vcovHC:

I have sandwich version 2.2-7 installed.

reordering huge data file
Dear R-experts,
My problem is how to handle a 10GB data file containing genotype data. The file is in a particular format (Illumina final report) and needs to be altered and merged with phenotype data for further analysis.
PERL seems to be an frequently used solution for this type of work, however I am inclined to think it should be doable with R.
How do I open a text-file, line by line,

Complete newbie - create microarray image from data file?
Hey
So sorry to be a total newbie, but i'm just finding my feet with R.
I heard on the grapevine i could recreate a scanned microarray image, or at
least get a good graphic of it from a just a data file.
I have .txt files for illumina beadarrays but no images cos the service we
used didn't send them. The 'beadarray' package seems to require TIFFs to get
the graphic output.

Error in sort(abs(diff(genomdat)))[1:n.keep] : only 0's may be mixed with negative subscripts
Hello everyone,
I`m trying to normalize and analize an illumina SNP array.
But when i`m trying to segmentate i`m getting an error:
Error in sort(abs(diff(genomdat)))[1:n.keep] :
only 0's may be mixed with negative subscripts.
I`ve tried everything to fix this but the error still occours.
Can anybody give me a tip?
Thanks in advance!

Tree question
I was under the impression that the tree method (e.g. as implemented in
rpart) was insensitive to monotonic transformations of the dependent
variable. e.g. Breiman Olshen et al. Classification and Regression
Trees state "In a standard data structure [a tree] is invariant under
all monotone transformations of individual ordered varaibles" (p. 57)
However, I get very different results

[LLVMdev] LLVM/Clang on Sparc64
Thanks to Jakob's work on Sparcv9 ABI in Clang and recent changes to
Sparc code generator, I am happy to announce that Clang can self host
itself on Linux/Sparc64 and on FreeBSD/Sparc64.
However, it still fails on a few unit tests and nightly tests,
primarily due to misaligned memory accesses in the code (See bugs
18482, 18500, 18502, 18536, 18693). Unlike other architectures,

[LLVMdev] Patch: Compiling LLVM in Sparc
I would prefer not to; they already live in a protected namespace, so
there is no need to mangle them except to protect them from exuberant
preprocessor defines, and this would be slightly out of style with
other public uses of enumerations in LLVM.

How to measure/rank ?variable importance when using rpart?

Thus, my question is: *What common measures exists for ranking/measuring

this be computed using R (for example, when using the rpart package)*

[LLVMdev] Patch: Compiling LLVM in Sparc
Hello,
The current version in SVN fails to compile in sparc machines since
gcc defines "sparc" as a macro in sparc machines that expands to 1
(see below) but Triple.h defines "sparc" as a enum constant.
$ cpp -dM /dev/null | grep sparc
#define sparc 1
#define __sparc__ 1
#define __sparc 1
The attached patch fixes this problem by renaming sparc to sparc_.
Thanks,
