Hello! I am crossposting this to R-help and BioC, since it is relevant to both groups. I wrote a wrapper for Entrez search utility (link for this is provided bellow), which can add some new search functionality to existing code in Bioconductor's package 'annotate'*. http://eutils.ncbi.nlm.nih.gov/entrez/query/static/esearch_help.html Entrez search utuility returns a XML document

I am using custom control for entering a date on the form. My date format is dd.mm.yyyy and this is also what the control returns to program. But ActiveRecord expects date to be formated as mm.dd.yyyy and thus saves wrong value to database. I have implemented method which corrects date fields prior to save to database, but it is clumsy. There must be a solution to configure ActiveRecord so it

Jun hi again! Sorry for bothering. Although I had no problem with building Windows package under Linux, I noticed that man pages are not processed as they should or maybe I have a problem with my setup. My package is called 'GeneticsPed'. Instead of HTML or text files I just got a GeneticsPed.Rd.gz in man directory of a package (this is within GeneticsPed_0.1.zip file!). The file

Hello! Can someone provide me an estimate or relevant source of information on how long is command winepath available or from wich version of wine? I would need this as I work on some R[1] package R2WinBUGS[2] that calls a Windows program WinBUGS[3] and that program needs windows paths. Currently winepath or parsing of .wine/config is used and I wonder if I can remove fiddling with .wine/.config.

Hello! I am trying to get specific fields from an XML document and I am totally puzzled.

Hello! I would like to use constrain to sum coeficients of a factor to 0 instead of classical corner contraint i.e. I would like to fit a model like lm(y ~ 1 + effectA + effectB) and say get parameters intercept effectA_1 effectA_2 effectB_1 effectB_2 effectB_3 where effectA_1 represents deviation of level A_1 from intercept and sum(effectA_1, effectA_2) = 0 and the same for factor B.

Dear R developers, I have encountered strange behaviour of fitdistr for gamma in recent R build i.e. 2.2.0. I have attached the code for data at the end of this mail so you can reproduce the problem. In short, I am able to run fitdistr under 2.1.0 without problems, while I get the following error under 2.2.0 (Version 2.2.0 Patched (2005-11-15 r36348)) > fitdistr(otm, "gamma") Error

Hello! Say I have a function foo1, which has argument ... to pass various arguments to foo2 i.e. foo1 <- function(x, ...) { foo2(x, ...) } Say that foo2 accepts argument arg1 and I would like to do the following: - if foo1 is called as foo1(x) then I would like to assign some value to arg1 inside foo1 before calling foo2 arg1 <- "some value" foo2(x, arg1=arg1) - if foo1 is

Hello! Looking on how people use optim to get MLE I also noticed that one can use returned Hessian to get corresponding standard errors i.e. something like result <- optim(<< snip >>, hessian=T) result$par # point estimates vc <- solve(result$hessian) # var-cov matrix se <- sqrt(diag(vc)) # standard errors What is actually Hessian representing here?
