download.file not working
Hi all, I'm trying to download a file from the net, and the download.file command leaves it corrupted, i.e excel cannot open it. It seems as if it's going ok, however.

Change the position of panel strips in a lattice plot.
Hi all, In lattice plots, is there any option to position the panel strips with text below each subgraph, instead of above? i.e. in: Depth <- equal.count(quakes$depth, number=8, overlap=.1) xyplot(lat ~ long | Depth, data = quakes) ,is there any way to make "Depth" appear below the subgraphs, instead of above? I've been looking through the lattice documentation and the list

moving average on irregular time series
Hi all, I wonder if there is any way to calculate a moving average on an irregular time series, or use the rollapply function in zoo? I have a set of dates where I want to check if there has been an event 14 days prior to each time point in order to mark these timepoints for removal, and can't figure out a good way to do it. Many thanks in advance! Gustaf Example data:

Preparing high quality figures with tiff as end result
Hi all, I'm currently preparing some figures that will be submitted to PloS One. In their guidelines they state that they will only accept figures in tiff or eps format, with the warning that eps figures will be converted to tiff format ( see http://www.plosone.org/static/figureGuidelines.action ). Because of this conversion, I figured I'd generate tiff-format figures from the beginning.

two-sample test of multinomial proportion
Hi all, This is perhaps more a statistics question than an R question, but I hope it's OK anyhow. I have some data (see below) with the number of tests positive to subtype H1 of a virus, the number of tests postive to subtype H3, and the total number of tests. This is for two different groups, and the two subtypes are mutually exclusive. What is the best way to test if the proportion of H1

x-axis order
Hi all, I have a time series which contain data collected weekly from week 26 to week 25 the following year. How do I plot this data, so that the x-axis is displaying the week numbers, ordered as in the data? Thanks in advance, Gustaf --- x<-c(26:52,1:25) y<-rnorm(52)+1:52 plot(x,y) ## How do I get the x axis to be ordered by the current ordering of x? -- Gustaf Rydevik, M.Sci. tel:

getting ISO week
Hi all, Is there a simple function already implemented for getting the ISO weeks of a Date object? I couldn't find one, and so wrote my own function to do it, but would appreciate a pointer to the "default" way. If a function is not yet implemented, could the code below be of interest to submit to CRAN? Best Regards, Gustaf --------------------

Set encoding when load()-ing workspaces?
Hi all, I hope that there is someone that can help me out here. I am trying to load() a workspace on os x (R 2.11.0) that was saved in windows XP (R 2.9). In that workspace, there's a data.frame with names that contain swedish characters. These characters become garbled, which is a major problem. >From the R windows FAQ, I read: "Note though that character data in a workspace will be

WHO Anthro growth curve macros and R
Hi all, I've got a project where I have to calculate weight-for-age Z-scores, preferably using the WHO standards. WHO have been very nice to publish macros for doing this in both STATA,SPSS, SAS and Splus formats (see http://www.who.int/childgrowth/software/en/), but for some reason have chosen not to use the free R alternative to Splus. In the Splus zipfile there are nine datafiles with a

Aggregate?
Hi All, I think i'm failing to undersatnd how aggregate() is supposed to work. example: test1<-sample(c(0,1),100,replace=T) test2<-sample(letters,100,replace=T) aggregate(test1,list(test2),sum) Error in data.frame(w, lapply(y, unlist, use.names = FALSE)) : arguments imply differing number of rows: 26, 0 I thought this would give me a list containing the number of ones that

reshape, direction=long: "multiple row names not allowed"
Hi all, for some reason I always get stuck spending hours when trying to use reshape or the Reshape package. Heaven knows why. My latest frustration (in 2.7.1, so ignore if this has been fixed): test<-data.frame(matrix(rnorm(42*4),ncol=4),rep(1:21,2),rep(c("a","b"),each=21)) reshape(test,varying=list(colnames(test)[1:4]),direction="long")

"utils" lacking namespace?
Hi all, A colleague of mine tried to install the package EMV, which had been removed from CRAN. she ran into some kind of trouble, R locked up, and she closed the program. Now when she starts R, "utils" can't be loaded which of course create an unworkable environment. Below I've copy-pasted the error message she gets when starting R. Any ideas on what went wrong, and more

The "$" operator and vectors
Hi all, I've run into a slightly illogical (to me) behaviour with the "$" subsetting function. consider: > Test A B 1 1 Q 2 2 R > Test$A [1] 1 2 > vector<-"A" > Test$vector NULL > Test$"A" [1] 1 2 > Test[,vector] [1] 1 2 Is there a reason for the $ operator not evaluating the vector before executing? best, Gustaf -- Gustaf

data frames with å, ä, and ö (=non-ASCII-characters) from windows to mac os x
Hi, I ran into this issue previously and managed to solve it, but I've forgotten how and am getting frustrated... I have a data frame (see below) with scandinavian characters in R (2.7.1) running on a Win Xp-computer. I save the data frame in an RData-file on a usb stick, and load() it in R (2.8.0) running on OS X 10.5. Now the name of the data frame and all factor labels with scandinavian

Avoiding overplotting of text.
Hi all, I am plotting some data, and use text() to get variable names next to points on the graph. What is the best way to make sure that these text labels are readable and not overlapping when two datapoints are close? I've tried using jitter(), but the effect is random and doesn't always give a good result. Any suggestions would be most appreciated. Best regards, Gustaf Example:

Vertical line in densityplot?
Hi all, I'm trying to get a vertical line at a specific point in a densityplot. abline seems to be what's required, but it doesn't align itself to the scale used in the plot. example: library(lattice) x<-rnorm(100) plot.new() densityplot(x) abline(v=0) ----- The line seems to use some other coordinate system. What kind of call do I use to make abline use the graph's

[Fwd: Re: Coefficients of Logistic Regression from bootstrap - how to get them?]
I think the argument supporting the use of bootstrap to determine coefficients, as opposed to just running linear regression on the whole dataset, is the comparison of Rsq and prediction errors between these two approaches - page 1502. There's a substantial difference in favor of the bootstrap approach. -- Michal J. Figurski Gustaf Rydevik wrote: > The url for the mentioned paper is
