Reading ASCII files
Dear all,
I need to read an ASCII file with diffent length lines.
This is what is contained in the file gene.txt:
1st line ID description snp_id genotype

Histogram
Dear all,
I have a surprising problem with the representation of frequencies in a
histogram.
Consider, for example, the R code:
b<-rnorm(2000,3.5,0.3)
hist(b,freq=F)
When I plotted the histogram, I expected that values in the y-axis (the
probability) varied between 0 and 1. Instead, they varied within the
range 0-1.3.
Have you got any suggestion for obtaining a correct graph with

linkage disequilibrium
Dear all,
I'm using the package "Genetics", and I'm interested in the computation of D'
statistics for Linkage Disequilibrium, for which the LD() command has been
realised. Unfortunately I don't find any reference on "how" the D' is computed
by the LD() function. In the package documentation it is generally referred as
"MLE" estimation, but

AW: Query: IRR Confidence Intervals
Hi Cristian,
I don't know about a R routine for exact CIs, but I found a function called
"ageadjust" using a gamma distribution approximation some time ago -take a
look at http://medepi.org/epitools/rfunctions/index.html.
That Webpage seems a bit outdated now, but the calculations given in the
ageadjust functions should still work, I think.
Maybe this helps;
regards
Heinrich.

smbd daemon running as wrong user ID
Hello,
I have a strange problem affecting samba-3.0.10-1.4E.12.2 on a Red Hat
Enterprise Linux AS release 4 system.
We have a multi-domain configuration here at University of Verona
(Italy). We use Samba as PDC for several faculties. Each faculty has its
own daemon instance and its own smb config file:

Odds Ratio from Logistic Model
Hi all.
A simple question.
Is there a function to compute the Odds Ratio and its confidence intervall, from a logistic model (glm(.......,family=binomial....). I've written my own, but certainly someone did a better job.
Thank you in advance,
Stefano

Is it possible to regenerate the index files?
Is it possible to regenerate the index files, on other conditions than
the mbox file being read?
For instance, it would be nice if I could regenerate the index for a
specific mbox whenever procmail delivers mail to it.
If theres no existing solution, would it be possible to make a small
script with something like "nc" that could send an imap command to
dovecot, so that dovecot would

Bug or new concept in formatC?
As a sequel to my previous mail on cut, formatC does not produce
what I have been taught is significant digits:
> x <- c(1.0793,1.0796, 11.0954, 11.0736 )
> formatC(x,digits=3,format="g")
[1] "1.08" "1.08" "11.1" "11.1"
(3,3,3,3) significant digits OK
> formatC(x,digits=3,format="f")
[1] "1.079"

Compilation of source package.
I have a samll package that works well and complies nicly on WinXP,
using R-2.4.1
Now I want to add a document so i make a folder inst\doc and put the
.tex and .pdf in there.
But the complation then crashes. Is this because the installin expects
some file to be present in inst if an inst folder is there?

pretty for a log-axis
Is there a function that does the same as pretty but on a log-scale?
Suppose you have
x <- exp( runif( 100, 0, 6 ) )
(which will between 1 and 403), then I would like to have a result like:
log.pretty( x )

Building a package under WIN2000 / rw2.0
I have an odd problem in building a package with only R-code in it.
I have a package mainly used by myself which I last build under R

Rounding?
I was a bit puzzed by:

[1] "6.6"
So I experimented and found:

[1] "6.6"
> formatC(6.650000000000001,format="f",digits=1)
[1] "6.7"
> round(6.6500000000000001,1)

FW: Installing BRugs
A funny thing happened when I wanted a student of mine to install Brugs.
Using the InstallPackages in the windows version, firts gives an erro, but trying again works flawlessly.
R version is 2.7.0 on WinXP.
Any explanation?

Margins on tables
It has long been a nuisance to me not being able to form margins on
multiway tables in a simple fashion, so i wrote margins().
In my opinion it should go into the base package. The code and the
documentation is in:
http://www.biostat.ku.dk/~bxc/R/margins/
Please help yourself, and enhance and rename as you see fit.

The .tex version of the manual in foo.Rcheck
In version 2.8.1, running Rcmd check on the package foo would leave the file foo-manual.tex in the folder foo.Rcheck.
But as of 2.9.0 only foo-manual.pdf and foo-manual.log are there.
Is this intentional?
Anyway it is inconvenient, because I would occasionally like to include the manual at the end of a set of exercises, and this was a convenient file to \input with a few select %'s added.
