Hello everybody, I am just trying to put together my first own CRAN-able package. I have completed the programming and my code works OK. But now when I perform R CMD check agsemisc_1.0-2.tar.gz and R gets to the step * checking examples ... I receive the following error message: > print(bwplot(Species~Sepal.Length, data=iris, panel=panel.bwstrip)) Error in rep(T, length(x)) : T used

Hello all, trying to prepare my first package for submission to CRAN I am stumbling over the "checking examples" step of R CMD check. I have some examples that produce more than one plot. I currently separate those plot calls by readline("Press <Return> for a plot including a density plot") or some such to have R wait before producing the next plot. This works OK

I am looking for a function like my.blockwisesum(vector, n) that computes sums of disjoint subsequences of length n from vector and can work with vector lengths that are not a multiple of n. It should give me for instance my.blockwisesum(1:10, 3) == c(6, 15, 24, 10) Is there a builtin function that can do this? One could do it by coercing the vector into a matrix of width n, and then use

I personally belong to an (apparently fairly large) group of R users who may be enthusiastic, but are statistical laymen due to a lack of formal education in the area. The

Hello everybody, I have a bunch of strings like this: "IBM POWER4+ 1.9GHz" "IBM RS64-III 500MHz" "IBM RS64-IV 600 MHz" "IBM RS64 IV 750MHz" "Intel Itanium 2 Processor 6M 1.5GHz" "Intel Itanium2 1 Ghz" "Intel Itanium2 1.5GHz" "Intel

Dear Lattice bit-meddlers, while within a panel function for xyplot, how can I find out the values of (effectively) xlim and ylim -- no matter whether they have been set explicitly or chosen by Lattice itself? I have just tried for an hour to find out, with no success whatsoever. I looked in Grid for something that would return such data, but got lost. I looked at tracebacks of panel calls,

Full_Name: Lutz Prechelt Version: 2.2.1 OS: WinXP SP2 Submission from: (NULL) (130.133.8.114) This command plot(0, 0, xlim=c(3, 5), ylim=c(0, 10, 17)) should complain about 'ylim' (because it has three elements). However, it does in fact (in my german error message at least) complain about 'xlim' instead: Fehler in plot.window(xlim, ylim, log, asp, ...) : ung?ltiger

Full_Name: Lutz Prechelt Version: 2.4.1 OS: Windows XP Submission from: (NULL) (160.45.111.67) I stack a number of data.frames using rbind. Each of these dataframes has a column 'authorname', which is a factor and a column author = unclass(authorname) as piecewise pseudonyms. When using rbind to stack these dataframes, R warns about invalid factor levels and inserts all NAs in the author

Dear alltogether, how can a delay like possible with par(ask=TRUE) be attained while using trellis-plots within a loop or something like that? the following draws each plot without waiting for a signal (mouse-klick), so par() does not work for that: library(nlme) for(i in 1:3) { fitlme <- lme(Orthodont) par(ask=TRUE) # does not work with trellis.... print(

In your data frames, 'y' is a category and the following comment in the code makes clear this is deliberate. if( !is.null(levels(xj)) ) { all.levs[[j]] <- levels(xj) facCol[j] <- TRUE # turn categories into factors } else facCol[j] <- is.factor(xj) The behaviour is compatible with S apart from the comment in the R help

This is not a bug, nor is the subject line true: both do accept factors but what they do with factors is undocumented. From the help (not 'man') page Performs *set* union, intersection, (asymmetric!) difference, equality and membership on two vectors. ^^^^^^^ so it is not said to work on factors. I disagree that what intersect() for

Dear R-devels, I am looking for a package (or some other infrastructure) for the following situation: I am doing a larger data evaluation. I have several dozen data files and do not want to keep the persistent data in the R workspace (for robustness reasons). I have several dozen R files, some for reading and preprocessing data files, others for doing plots or analyses. I will make frequent

Dear friends of lattice, I know how to position trellis plots with print(...,split,more=T) or (...position). Sometimes I wish I had something like the old "par(mfcol=2, mfrow=3)" mechanism, where the next free viewport is automatically chosen. I tried fiddling with grid-viewports, but could not find an easy solution. Did I miss something? Dieter Menne

Ajay, thank you very much for picking up that age-old habit of posting summaries. It existed years ago on s-help and I find it is still a great thing: I would not have bothered to read your original question nor the answers you got, but I did read the summary -- and I learned something quite interesting! Maybe some others who receive multiple non-elementary answers to their questions could

Dear r-helpers, Does anyone have a straightforward example of putting together three unrelated (expect for a common y-axis) xyplot() figures in what would be in base graphics a par(mfrow = c(1, 3)) arrangement? _____________________________ Professor Michael Kubovy University of Virginia Department of Psychology USPS: P.O.Box 400400 Charlottesville, VA 22904-4400 Parcels: Room 102

Hi, First, I do some calculation, then a plot. Add some lines and texts to the plot. Second, do some further calculation, then a plot. Add again some lines and texts to the plot. Third, do some further calculation, then.... Fourth, ..... After a plot is complete (means the plot itself, lines and texts) I would like to click 'enter' to see the next complete plot (again the plot itself,

Hello: What happens in the auto-checks on R-Forge and CRAN with code using par(ask=TRUE)? Is this routine, or can it create problems? The fda package uses ask=TRUE to provide the user with a way to examine a group of plots. In the past, I've marked those tests in \examples with \dontrun. However, I wonder if that is necessary. I tried it on Windows using R
