How long is winepath available?
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.

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,

Constrain coefs. in linear model to sum to 0
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.

Re: Cross-building R packages

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

Hessian from optim()
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?

Wish/suggestion: add output of citation() to package "manuals" (PR#9009)
Dear R core, influenced by recent panel discussion in Vienna I think that it would be nice to add package specific output of citation() function to package reference manuals. I think that apropriate place would be just after fields from DESCRIPTION file. This will be OK for CRAN, but not for locally installed packages as there is not reference manual there (at least on my linux box) - why is this
