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,

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'*.

Programming/scripting with "expressions - variables"
Hello to Rusers!
I am puzzled with R and I really do not know where to look
in for my problem. I am moving from SAS and I have difficulties
in translating SAS to R world. I hope I will get some hints 
or pointers so I can study from there on.
I would like to do something like this. In SAS I can write 
a macro as example bellow, which is afcourse a silly one but 
shows what I don't know how

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.

Re: Cross-building R packages
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

Global setting for na.rm=TRUE
Hello!
Is it possible to set na.rm=TRUE in a global way? I'am constantly

be carefull with this when developing some code, but not necesarilly
so in data analysis.

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.

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

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

effectA_2
effectB_1
