similar to: Fishy error with NAMESPACE when checking package

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?

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.

Did not seem to reach Saikat DebRoy, this might be the forum.

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 1.9.0. The operation system is Win2000 5.00.2195, Service Pack 3 When I do: c:\stat\r\rw2000\bin\Rcmd install --docs=normal --build --library=c:\stat\R\bxc\library c:\stat\R\bxc\library.sources\xx then after updating help pages I get: preparing package xx for

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"

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

I run Windows XP. and in a command window I get: > c:\stat\r\R-2.13.1\bin\i386\Rcmd Sweave Lexis.rnw Error in length(arg) : 'arg' is missing Calls: <Anonymous> Execution halted AND: > c:\stat\r\R-2.13.1\bin\i386\Rcmd Sweave --help Error in length(arg) : 'arg' is missing Calls: <Anonymous> Execution halted BUT: > c:\stat\r\R-2.13.0\bin\i386\Rcmd 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}

Consider the following two specifications of a model: library( splines ) x <- 1:100 y <- rnorm( 100 ) w <- rep( 1, 100 ) A <- factor( sample( 1:2, 100, replace=T ) ) B <- factor( sample( letters[1:4], 100, replace=T ) ) summary( lm( y ~ ns( x, knots=c(30, 50, 70 ), intercept=T ):A - 1 + B ) ) summary( lm( y ~ ns( x, knots=c(30, 50, 70 ), intercept=T ):A - 1 + B:w ) ) The

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).

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:

Sometimes you want to compute the physical size of a plot based on data. In R itself this is no problem. But is there a way to compute the values of height and width in S-weave, say: <<graph,fig=TRUE,height=xx,width=yy>>= where xx and yy are computed and not physically written in the document?

coef() and vcov() have different dimensions if a model contains alised parameters as the following example illustrates. A search on "alised" gave noting as far as I could see. Is this a known bug?

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.

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 ) [1] 1 5 10 50 100 500 Bendix C. ---------------------- Bendix Carstensen Senior Statistician Steno Diabetes Center Niels Steensens Vej 2 DK-2820 Gentofte Denmark tel: +45 44 43 87 38

The function addmargins() adds margins to a table, but returns a matrix. But even after converted to a table the print.zero="." option of print.table() does not work: > x <- sample( 1:7, 20, replace=T ) > y <- sample( 1:7, 20, replace=T ) > tt <- table( x, y ) > tx <- as.table( addmargins( table( x, y ) ) ) > print( tt, zero.print="." ) y x 1 2

Here is a piece of code fitting a model to a (part) of a dataset, just for illustration. I can extract the random interaction and the residual variance in group meth==1 using VarCorr, but how do I get the other residual variance? Is there any way to get the other variances in numerical form directly - it seems a litte contraintuitive to use "as.numeric" when extracting estimates,
