Re: [Rd] corrupt data frame: columns will be truncated or padded with NAs in: format.data.frame(x, digits = digits)
James, thanks for the response. I understand now my puzzle. tmp <- data.frame(y1=1:4, f1=factor(c("A", "B", "C", "D"))) tmp$y2 <- NA tmp[1:2, "y2"] <- 2 Does the job. I see that I should add a full column. In my case adding full column of NAs and then adding values, solves my problems. Thanks to all. james.holtman at convergys.com

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.

F90
Hello! Has anyone successfully compiled F90 sources in R-package? I found the same question on r-devel list from 2002 and I wonder if there is any progress. I heard that g95 and gfortran can be usable. And one more thing. I have a program written in F90 and lets suppose that compiler is not a problem. I've read manual 'Writing R Extensions' and successfully loaded one F77 subroutine

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?
