spam on R lists --> refuse mail??
We get caught occasionally, and we all receive spam; sorry for the last one (on R-help). Of course, there will never be a 100% sure prevention... Question is what should happen when mail from R-help to an adressee is refused with the following message : At least I won't be able to easily send e-mail to them {and am not willing to use a non-easy way}.... ----- Transcript of session

Reading a file line by line - separating lines VS separating columns
Hello all. I wish to read a large data set into R. My current issue is in getting the data so that R would be able to access it. Using read.table won't work since the data is over 1GB in size (and I am using windows XP), so my plan was to read the file chunk by chunk and each time move it into bigmemory (I'll play with that when the time will come, maybe ff is better ?!). I encountered

How do I sample "cases" within a matrix?
Hi R community, I am trying to obtain a sample from a matrix but sample(my.matrix) doesn't do what I need. I have a matrix of 1287 interactions between the species in columns and the species in rows and I want to obtain a smaller matrix with say, 800 interactions, that may or may not have the same number of columns and/or rows (i.e., some interactions may not be retrieved in a smaller sample).

[LLVMdev] buildbot failure in LLVM on clang-x86_64-ubuntu-gdb-75
This bot seems kind of flaky. In the last 100 builds, it has failed "gdb-75-check" 22 times with what is either a linker error or a missing header (or both?): gdb compile failed, /usr/bin/ld: error: /home/buildslave/osuosl_slave/clang-x86_64-ubuntu-gdb-75/clang-tests/build/gdb/testsuite/gdb.trace/pendshr1.c.o: requires dynamic R_X86_64_PC32 reloc against 'pendfunc1' which

Strange Font
So anyway, I have been using linux for years now, currently Fedora 12, and just recently I opened a box and found several of my old windows games. Starcraft, Heroes, Age of Empires, Stronghold, etc, some of which I installed. Then I came to Masters of Orion. This game I figured my crappy netbook could handle, and I get a bunch of "??????????" s in place of the actual text in the

How to catch an error using try
Sometimes the following function call causes a database exception: > gene.seq <- getSequence (id=gene.map[,"ensembl_transcript_id"], type="ensembl_transcript_id", + seqType="3utr", mart=hmart) I understand the above function must be called by try to capture the eventual error. WHat is not clear to me is how to realize that an

conflicting imports despite using importFrom in NAMESPACE
Dear all, It is my understanding that using 'importFrom' in the NAMESPACE of a package allows to avoid conflicts between different packages defining objects with identical names. However, I can still see conflicts while loading the package using 'library'. Here is a toy example, with a package 'foo' importing 'as.igraph' from the igraph package, and 'nj'

Hi, I am working with lists whose terms are lists whose terms are lists. Although the real ones contain locuslink identifiers and GO annotations (I work with the Bioconductor GO) package, I have prepared an simplified example of what I have and what I would like to do with it: Imagine I have a list such as:

installing packages on MAC os X
Hello, I've just downloaded and installed the RAqua onto my Mac and I have R up and running fine. Now I'm trying to get 'ape' downloaded and installed and having quite the difficulty. I am following the directions specified under 'Installing packages' where packages can be downloaded and installed from within R. I get the following error messages: 1: argument

I suppose that once you've got a 6502 working, adding support for a 4510 shouldn't be too difficult....

[LLVMdev] MOS6502 target
Well, the stack pointer be a single byte, so pushing things on there doesn't work terribly well. Assuming I pass by reference, that's 128 values absolutely total before it wraps around and silently clobbers itself. It means single byte values will be incredibly inefficient... Tricky stuff. I'm lucky on the C64 since it's rare to exit back to the kernel with machine language apps

Centos 8 and xfs_quota
Folks I'm trying to use xfs_quota to keep track of disk space usage for my users. The documentation states that I should specify "uquota" as an option on the mount data in /etc/fstab. Yet, I cannot find the entry in fstab that corresponds to the Logical Volume that ends up being mounted on /home1. The system in question was installed on a single disk system. Later, after

[LLVMdev] LLVM porting Plan9 (probably stupid question)
I am not sure whether this would work or if there are other limitations that would block this very simplistic porting strategy to work. Since it looks so easy on paper, I expect it to be more complicated otherwise it would probably already have been done. According to the LLVM FAQ the important dependencies for LLVM are a unix-type shell and sed [1], but those dependencies are provided by APE

Error with Rcmd check library --as-cran
Hello all, I was checking the newest update of my library before submitting it to CRAN, using R 2.15.0 and Rtools for Windows 215 using Rcmd in the Command Prompt, on my x64 Windows7 laptop. I recently heard that for checking packages for CRAN submission one should use the option --as-cran; previously I was submitting packages, so I was trying that for the first time. The check proceeds fine

peering inside functions in a package?
Let's say I would like to look inside the function corBrownian in library (ape). When I type in the function name I get the following, which is not nearly the detail that goes into this function. I am wondering how to begin cracking this function open (and others) so I can learn more about it and perhaps code my own corClass one day. Thanks. > corBrownian function (value = 1, phy, form

Binary Tree Testing in "ape" package (a bug?)
Dear all, I was testing the wonderful package APE. However upon testing a particular Newick's format tree - which I think to be a non-binary tree - it yields different result as expected. > library(ape) > tree.hiv <- read.tree(text="(rat,mouse,(human,chimp));") > is.binary.tree(tree.hiv) [1] TRUE Was that a bug in APE package? - Gundala Viswanath Jakarta - Indonesia
