Hi, Suppose I have a multidimensional array: tmp <- array(1:8, c(2,2,2)) is there a function out there that, given a one-dimensional array index, will return the separate indices for each array dimension? for instance, tmp[8] is equivalent to tmp[2,2,2]. I'd like to derive the vector (2,2,2) from the index 8. thanks, Brad Buchsbaum

How about this. Its not as 'swish' as Doug's response, but it might be a little simpler to think about and adapt... # show the test vector > tmp [1] A B C B C A C B A A B Levels: A B C > # create a named vector to store the number of occurences of each level > index <- numeric(length=length(levels(tmp))) > names(index) <- levels(tmp) > index A B C [1] 0 0

Hi, I have an S4 class that inherits from "array" but does not add generic implementations of the "[" method. A simplified example is: setClass("fooarray", contains="array") If I create a "fooarray" object and subset it with a one-dimensional index vector, the return value is of class "fooarray". Other variants (see below), however,

Hi, I am working on writing some S4 classes that represent multidimensional (brain) image data. I would like these classes to support standard array indexing. I have been studying the Matrix and EBImage (http://www.bioconductor.org/packages/1.9/bioc/html/EBImage.html) packages to see how this is done. When using objects of the "array" class directly, R distinguishes between the calls:

Hi, I'd like to plot 4 groups of data using xyplot and panel.superpose so that the points are overlayed on a single plot. For each group of data I'd also like a loess smoothed function (using panel.loess). I have tried the following: xyplot(series ~ time | gr, data=etable, panel = function(x,y, ...) { panel.superpose(x,y, ...) panel.loess(x,y,span=.15)

I'm having problems copying and saving lattice graphs using R-1.4.0 under Win2k. It seems I've see this alluded to recently in R-help. If I do the following example: > data(quakes) > xyplot(long ~ lat , data = quakes) And then try to copy or save the graph as either a metafile or bitmap or if I use any of the bitmap/metafile devices via (for example) >

Hi all, I'm trying to test a repeated measures model with random effects using the nlme library. Suppose I have two within subjects factors A, B both with two levels. Using aov I can do: aov.1 <- aov(y ~ A*B + Error(S/(A+B)) following Pinheiro and Bates I can acheive the analagous mixed-effects model with: lme.1 <- lme(y~A*B, random=pdBlocked(list(pdIdent(~1),pdIdent(~A-1),

Hello, All: What facilities exist for plots and tables of data in the standard MediaWiki software beyond the obvious standards? The standard MediaWiki tables and graphics capabilities seem to me to be rather clumsy, and I wonder if I'm missing some available extensions? The standard MediaWiki tables are described in a Wikipedia article on "Help:Table".

Dear all, I would like to make a large scatter plot created with R available as an interactive web graphic, in combination with additional text-annotations for each data point in the plot. The idea is to present the text-annotations in an HTML-table and inter-link the data points in the plot with their corresponding entries in the table, i.e. when clicking on a data point in the plot, the

SVG starts to become more useful in browsers like Firefox, OmniWeb, Opera and soon Safari. There is a couple problem. Since no browser support svg embedded with img one need to fall back to html from: <object data="/path/to/img.svg" type="image/svg+xml" width="512" height="384">Alt text</object> Second, one need to write the width

Dear R-list, I have a partly comma separated partly underscore separated string that I am trying to parse into R. Furthermore I have a bunch of them, and they are quite long. I have now spent most of my Sunday trying to figure this out and thought I would try the list to see if someone here would be able to get me started. My data structure looks like this, (in a example.txt file) Subject

Tom, I note that you use Visio for your network diagrams. Have you considered placing SVG source in CVS? I believe Visio can import/export SVG now. If you''re not using the newest version, I think the VDXtoSVG project can convert Visio 2002 VDX files to SVG. If you''re using a version older than that, I doubt an acceptable solution is achievable. VDX to SVG

Hello, All: ????? I'm unable to control the font size in plots to svg.? Consider the following: svg('cex-svg.svg') cex. <- 5 plot(1:2, cex.axis=cex.) text(1:2, 1:2, c('as', 'DF'), ????????? cex=cex.) dev.off() ????? When I open this in Gimp 2.10.4, the font size is tiny.? I also tried: svg('cex-svg.svg', width=15, height=15, pointsize=24) cex.

I eliminated software-bridge( using iperf3 bandwidth/latency on the host and guest was almost the same) and disk write(using qemu-img convert src dest file both on the host and guestvm was comprable) being the issue. Next I profiled both sshd and qemu-img during the conversion phase using bpftools (profile and tcptop) and this is what i see. Time (min) File Size (KB) sshd RX (KB) tcptop

I would like, in R, to embed a bitmap image /by link reference/ into a SVG plot image. Images may be included in an SVG by http://www.w3.org/TR/SVG/struct.html#ImageElementHrefAttribute link reference , or even http://en.wikipedia.org/wiki/Data_Uri data , for example: My objective is to reduce the size of the SVG image files I am generating (My plots have about 10? points: that's a

the link_to command is really nice, especially with confirm built in - wondering if there is a way to use it with SVG images since SVG doesn''t seem to work with image_tag I can display svg images (in Firefox) with the following code: <embed width=32 height=32 src="/images/quit.svg" type="image/svg+xml"></embed> "normal" link_to code:
