Positions in Computational Biology
Hi, We're looking for a number of people to join our group (Applied Computational Biology and Bioinformatics -- ACBB) and applying state of the art techniques (see for example, xmap.picr.man.ac.uk) to integrate, analyse and interpret datasets arising from the latest generation of microarrays (including exon, SNP and tiling arrays), quantitative mass-spectrometry and next generation sequencing. We write a lot of Bioconductor and R code - hence my posting to this list... I've i...

File permissions and packages, openVignette
Hi, I've got a quick question about file permissions and packages... I'm creating my own package, and am having problems with its vignette not being seen when I install it into R... As I understand it, the permissions of the source tree should be as follows: o Directories - drwxrwxr-- o Files - -rw-r--r-- Everything builds and runs through 'R CMD check' fine with

Apply and its friends
Hi, Forgive a very basic question... I need to take two lists-of-lists, and apply a function to each pair of elements in the lists to return a single list... For example l1 <- list(1:5,6:10,2:15) l2 <- list(1:8,4:12,1:19,4:20) I could easily do an lapply across each of them, but is there a function that does a sort-of pairwise-apply across both together? Does anybody know of a good

[BioC] make.cdf.package: Error: cannot allocate vector of size 1 Kb
My machine has 8GB memory. I had quit all other programs that might take a lot of memory when I try the script (before I post the first message in this thread). The cdf file is of only 741 MB. It is strange to me to see the error. On Mon, Dec 28, 2009 at 2:38 AM, Wolfgang Huber <whuber at embl.de> wrote: > Dear Peng Yu > > how big is the RAM of your computer? You could try with

Optimising code
Hi, Does anyone have any advice on speeding up R functions (short of re-implementing them in C :-) )? I have a function that applies a wilcoxon test to 12 sets of about a quarter of a million pairs (and takes about 3 hours). I've replaced the inner loop I had originally with a function call via mapply, and also considered different approximations of the wilcoxon, rather than that which is

.First.lib doesn't appear to be running after calling library()
Hi - so I've dusted off the C bits of my brain and gotten a library written for my package... It passes R CMD check ok, and I've put a file called '.First.lib.R' in the pacakge's 'R' subdirectory. Its permissions are 644. It says: .First.lib <- function(lib,pkg) { library.dynam("foo",pkg,lib); require(affy,quietly=TRUE); } I build and INSTALL

R CMD CHECK and require() / library() methods
Hi, I have a piece of code that decides at runtime whether to load a data package (and which package to load). This is then done with a call to: library(x) (where x is a character variable containing the package name). This causes R CMD check to throw out a warning: 'library' or 'required' calls not declared from: x Does anyone have any suggestions as to a fix or

Selecting font sizes graphics device
Dear all, Im' using matrix() and layout() to set up a fairly complex plot... I was wondering if anyone can point me to something that describes the appropriate incantations to determine, given a text string, the maximum font size that will allow it to fit into the current plotting area without being trunucated? best wishes, Crispin --------------------------------------------------------

RMySQL and stored procedures
Hi, I use RMySQL to connect to MySQL server where I have a couple of stored procedures. I know that the function for the stored procedures "is not yet implemented", but I was trying to get around the problem connecting like that: drv <- dbDriver("MySQL") con <- dbConnect(drv,user=MyUser, password=MyPasswd, dbname=MyDBName, host=MyHost, client.flag="196608"

Matrices with a single column
Hi, I've got a quick question about what happens when indexing into matrices with a single column. I was wondering if anyone can help ... For example: > x <- matrix(1:10) > y <- cbind(x,x) > x[4:6,] [1] 4 5 6 > y[4:6,] [,1] [,2] [1,] 4 4 [2,] 5 5 [3,] 6 6 > class(x[4:6,]) [1] "integer" > class(y[4:6,]) [1] "matrix" It seems that R

Creating packages in 1.8
Hi, I decided to upgrade to 1.8 today... :-) Anyway, we are writing our own package that is dependent on a bioconductor library - 'affy'. I've checked and when I fire up R, library(affy) behaves as expected... so it all seems to be installed and OK... In the DESCRIPTION file in my package source I have the line: Depends: affy When I run R CMD check simpleaffy I get to: ... *
