Test for argument in ...
Hello!

Sweave and \input or \include LaTeX commands
Hello! I was just wondering if Sweave can work with \input or \include LaTeX commands. So, is it aware of such a possible hierarchy in documents. I would test that, but I don't have such a report available at the moment. I thought of that when I was writting shell script for Sweave from command line and I have solved that part there. -- Lep pozdrav / With regards, Gregor GORJANC

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 to get mode (the most frequent value in distribution)?
Hello! I have a continous distribution and would like to get mode (the most frequent value in distribution). I easily found mean, median and other basic thing but not mode function. Can anyone help? I know there my might be problems with multiple modes, but still I think that there should be a mode function in R. Please send mail to R-help list and me, so I can get response faster. Thank

Upgrading R
Hello! New version of R has came out and I would like to thank to all developers on this matter. So I should probably upgrade. Fine and no problem. For windows I just grab the latest precompiled binnaries and install them. Then I see a report on a bug, which is or will be fixed in pacthed version. So I need to get binnaries from patched build and install them, right? How often do you people

Random seed problem in MCMC coupling of chains
Hello! I am performing coupling of chains in MCMC and I need the same value of seed for two chains. I will show demo of what I want: R code, which might show my example is: niter <- 3 nchain <- 2 tmpSeed <- 123 for (i in 1:niter) { # iterations for (j in 1:nchain) { # chains set.seed(tmpSeed) a <- runif(1) cat("iter:", i, "chain:", j,

Fitdistr and MLE for parameter lambda of Poisson distribution
Hello! I would like to get MLE for parameter lambda of Poisson distribution. I can use fitdistr() for this. After looking a bit into the code of this function I can see that value for lambda and its standard error is estimated via estimate <- mean(x) sds <- sqrt(estimate/n) Is this MLE? With my poor math/stat knowledge I thought that MLE for Poisson parameter is (in mixture of LaTeX

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.

Converting integers to chars i.e 1 to "01"
Hello! I am producing a set of images and I would like them to be sorted by names I give. I was able to produce my names and add integer to them. That is easy. But my problem lies in sort of file from this process: figure_10.png figure_11.png figure_12.png ... figure_1.png figure_20.png ... So I would like to convert integers to something like 01 if upper limit for this conert is 10 or 001

hist and truehist
Hello! Up to now I have been using hist() to display the distributions. Howevere, I noteiced strange numbers on y (vertical) axis, if I used probability = T or freq = F option. I thought it is a bug and launched the R-bug system and found some posts on that matter. Brian Ripley responded to one, that one should look at truehist() for that. Ok I can use truehist() if I want to see the ratios
