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

Test for argument in ...
Hello!
Say I have a function foo1, which has argument ... to pass various
arguments to foo2 i.e.
foo1 <- function(x, ...)

Say that foo2 accepts argument arg1 and I would like to do the following:
- if foo1 is called as foo1(x) then I would like to assign some value to
arg1 inside foo1 before calling foo2
arg1 <- "some value"
foo2(x, arg1=arg1)

I was reading R-intro and I have some suggestions:
R-intro.html#A-sample-session
rm(fm, fm1, lrf, x, dummy)

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.

Making a patch
Dear R developers,
is there a preferred format or strategy for making a patch to
contribute to a package that is maintained by R-core? Berwin Turlach
and I have written a very minor extension to lmeControl to allow it to
pass an argument to nlminb for the maximum number of evaluations of
the objective function. I've edited the nlme/R/lme.R and
nlme/man/lmeControl.Rd files. I can diff the

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

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.

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?

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:

nchain <- 2
tmpSeed <- 123
for (i in 1:niter) { # iterations
for (j in 1:nchain) { # chains
set.seed(tmpSeed)

Is there any way to test if R is running on a Mac? I usually use

Hello!
I am producing a set of images and I would like them to be sorted by names

figure_1.png
figure_20.png

So I would like to convert integers to something like 01 if upper limit for
