HTML-documentaion on NT
Once you hae in stalled Guido's NT port of R it is nice and easy to install the add-on packages too. However, it would be nice to have links to the documentation of the functions in all the packages from the "All Installed Functions" html-page, and not have to go through each of the packages. Is there a utility somewhere to do this? Bendix \\\|///

Ordered factors , was: surrogate poisson models
For ordered factor the natural contrast coding would be to parametrize by the succsessive differences between levels, which does not assume equal spacing of factor levels as does the polynomial contrasts (implicitly at least). This requires the contr.cum, which could be: contr.cum <- function (n, contrasts = TRUE) { if (is.numeric(n) && length(n) == 1) levs <- 1:n

I never understood that why is the value returned by as.date function in the library(survival) never matches with the description given in the help file: Following is the extract from ?as.date Description: Converts any of the following character forms to a Julian date: 8/31/56, 8-31-1956, 31 8 56, 083156, 31Aug56, or August 31 1956.

Rounding?
I was a bit puzzed by: > formatC(6.65,format="f",digits=1) [1] "6.6" So I experimented and found: > formatC(6.6500000000000001,format="f",digits=1) [1] "6.6" > formatC(6.650000000000001,format="f",digits=1) [1] "6.7" > round(6.6500000000000001,1) [1] 6.7 > round(6.650000000000001,1) [1] 6.7 > version

Handling dates
I have a problem with some functions handling dates, in packages 'date' and 'survival' (they seem to be identical). For instance, from the documentation, -------------------- mdy.date {survival} R Documentation Convert to Julian Dates Description Given a month, day, and year, returns the number of days since January 1, 1960. Usage mdy.date(month, day, year, nineteen = TRUE,

Building a package under WIN2000 / rw2.0

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? This is how the thing progress is on my command promp:

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?

This is how I get the month names from within R: > mon <- rep(strptime("01/01/1952", format = "%d/%m/%Y"), 12) > mon$mon <- mon$mon + 0:11 > mnam <- months(mon, abbreviate = F) > mnam [1] "januar" "februar" "marts" "april" "maj" "juni" "juli" "august"

relevel expansion suggestion
To the R developers, The discussion below reminded me that I think it might be a good idea to take the Relevel function from the Lexis package and replace relevel in stats with it. This is really nothing special for epidemiology. It is fully compatible with the existing relevel (it actually contains the relevel code almost verbatim as a subset), but it has the extra functionality of combining

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.

Figure environment and includegraphics options from Sweave
Tha handy thinb about the fig=TRUE option in Sweave is that you do not have to bother about filenames and starting and stpping the device. I want the the resulting LaTeX to look as: \begin{Schunk} \begin{Sinput} > x <- seq(-2 * pi, 2 * pi, 0.1) > plot(x, cos(x), type = "l", lwd = 4) \end{Sinput} \end{Schunk} \begin{figure} \includegraphics[width=0.6\textwidth]{xx-001}

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"

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.

print format for difftime
Has anyone written a function that will print a difftime in the form: hh:mm:ss or yy-mm-dd hh:mm:ss depending on the actual size. (sloppy notation for months/minutes, but surely you get the point).
