Hello! In my opinion read.fwf()'s behaviour of header is not really useful. Say I have the following data: col1 col2 col3 123 123 123 a b 1234 12 1234 65.4 4.5 Now if I want to read this data into R I can not use read.table due to missing fields. read.table(file="test.txt") Error in scan(file, what, nmax, sep, dec, quote, skip, nlines, na.strings,

Hello to everyone! I have built CRAN task view for genetics. For now I have not submit it to CRAN yet and it can be accessible from: http://www.bfro.uni-lj.si/MR/ggorjan/software/R/Genetics.html http://www.bfro.uni-lj.si/MR/ggorjan/software/R/Genetics.ctv I have not submitted it to CRAN, since I would like first some opinion about it.

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 writing some functions and I repeatedly acces internal factor codes. I figured out that internal codes are 1:n where 1 represents 1st level, 2 2nd level etc. This is not documented and I wonder if this is on purpose and subject to change or would be a good idea to add this to documentation for factor? I can prepair a pacth if this is accepted. -- Lep pozdrav / With regards,

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.

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! Data.frames have new rownames funcionality, however in use of colnames<- in R-devel "changes" this.

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?

Dear R developers, I noticed that core R distribution functions return NaN, when parameter values are out of parameter space. I have looked in source code and found that warnings and return of NaN are done internally in C code. For dgamma.c the line 49 is: if (shape <= 0 || scale <= 0) ML_ERR_return_NAN; OK. How should this be implemented if distribution functions are written
