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

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. Does anyone have an idea of what's going on? regards, Gustaf Rydevik ---- >download.file(url="http://www.who.int/entity/whosis/whostat2006_demographics.xls",destfile="whodem.xls") trying URL

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

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

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

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")

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:

Rahul Agarwal Analyst Equities Quantitative Research UBS_ISC, Hyderabad On Net: 19 533 6363 hi let me explain you the problem we have a database which is in this format Stocks 30-Jan-08 28-Feb-08 31-Mar-08 30-Apr-08 a 1.00 3.00 7.00 3.00 b 2.00 4.00 4.00 7.00 c 3.00 8.00 655.00 3.00 d 4.00 23.00 4.00 5.00 e 5.00 78.00 6.00 5.00 and we have a query

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:

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.

Hi all, I'm writing a function that will automatically generate a report based on answers to a questionnaire. The exact questions and answers to the questionnaire can vary. One of the question types is in a "matrix" format, where the agreement to several statements can be indicated on a scale. I'm planning to plot this on a multilevel barplot, and only labeling each "bar

Hi all, I'm trying to generate a plot containing a scatterplot, with marginal densityplots for x and y. However, when I try to generate a vertical densityplot, I get the message "warning: can't clip to rotated viewport", and nothing shows up. I'm probably misunderstanding how viewports are meant to be used, so if someone could give me a hint, I'd be most grateful. my

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 --------------------

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

Hi All, Two years back, I posted a small function for getting the ISO 8601 defined week number of a date (such as the week number used in all Swedish calendars), in a os-independent manner. I've since discovered an inaccuracy in that code, and so I thought I'd repost the corrected version. Hopefully this will come in handy for someone searching the mailing list archives in the future.

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

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

Hi all, I believe I've run into this before, but I seem to have totally forgotten. No headway in the last couple of hours either. How do I make sure that points and margins remain the same absolute size as I change the resolution of a device? (I'm running 2.9.1 patched, on a Win XP-machine) Many thanks in advance, Gustaf Ps: As an afterthought, might it be that this behaviour is
