Hello r-help, As far as I've seen, there is no function in R dedicated to sampling from a discrete distribution with a specified mass function. The standard library doesn't come with anything called rdiscrete or rpmf, and I can't find any such thing on the cheat sheet or in the Probability Distributions chapter of _An Introduction to R_. Googling also didn't bring back anything.

Hi R-devel I use the packages RGtk2 and cairoDevice. The cairoDevice package has a few stand-alone functions, plus "asCairoDevice" which depends on RGtk2 and calls require(RGtk2). So cairoDevice lists RGtk2 under "Suggests" in the DESCRIPTION file. It can not Import RGtk2 because that would force all users to install RGtk2. The upshot of this is, if you *import* the RGtk2

When using a gtkDrawingArea as a Cairo device I very often encounter the error: "figure margins too large" Even for the below "getting started" example from http://www.ggobi.org/rgtk2/ this is the case. > win = gtkWindow() > da = gtkDrawingArea() > win$add(da) > asCairoDevice(da) [1] TRUE > plot(1:10) Fehler in plot.new() : Grafikr?nder zu gro? > Also

Dear all, I use gtkImageFromFile to display an image. Then I want to do some gsignal to handle mouse event. I click the mouse and move a another position and release. I can get the position of the firs click and the release position, then I would to draw a rectangle to display the region I have selected. I need some hints on what functions should I look for. I tried to google but don't know

I realize that this question has been asked before (2003); From: Yi-Xiong Zhou Date: Sat 22 Nov 2003 - 10:57:35 EST but I am hoping that the answer has changed.

Hi R users, I would like to create an image using three matrices which contain the values of Red, Green, and Blue of each pixel, i.e. one matrix which has values of red, one which has values of green, and one which has values of blue. The values are between 0 and 1 instead of 0-255. I have obtained the matrices using the getChannels of pixmap library. I wonder if anyone knows how to create the

If I use Speex, JSpeex actually, to compress an otherwise valid wave file with zero lengths in the header would it impact the compression at all? Here's what I'm doing during compression in Java: AudioFormat wavFormat = ais.getFormat(); AudioFormat speexFormat = new AudioFormat(SpeexEncoding.SPEEX_Q5, wavFormat.getSampleRate(),

R is quite a powerful environment. Here's a small way it could be even better. I wanted to change the working directory, so I tried the obvious thing > cd("foo") Error: couldn't find function "cd" Then I looked for `directory' in the FAQ but found nothing. A search for directory in the introduction also turned up nothing. A Google search for "gnu R

Hi, dudes I got a question here. When I run "rake db:migrate" in 3rdrail, it throws an error: D:\ruby\bin\ruby.exe: no Ruby script found in input (LoadError).

Full_Name: Hans Dieter Version: 2.6.1 OS: Windows Submission from: (NULL) (217.93.95.129) Hi, I build a GUI with RGtk2 and used an GtkImage to display pictures like jpegs and others. This works but if I load a gif-Image it's not animated. It show's only the first picture, in general an GtkImage can display an animated gif. Greetings

I am not too familiar with Cairo and RGtk2 and have the following problem: I have a container with two GTK drawing areas converted into Cairo devices. I know that I can set the current drawing context e.g. using dev.set(). But this is tedious. How can I set the context using the objects da1 or da2? w <- gtkWindow() w$setSizeRequest(400, 400) vbox <- gtkVBox() da1 <- gtkDrawingArea()

I try to overlay a plot inside a gtkDrawingArea with a button (or any other widget). I tried to put both into a gtkFixed container. But this does not work, no printing occurs. Does someone know a solution? What I tried: w <- gtkWindow() w$setSizeRequest(400,400) fx <- gtkFixed() da <- gtkDrawingArea() fx$put(da, 100, 100) asCairoDevice(da) par(mar=c(0,0,0,0)) plot(1:10) btn.1

Has anyone here using VegaStream FXO with asterisk? I just got the Vega 50 10 FXO and all I could manage by now is to get outgoing calls. Any pointers and a script sample would be appreciated. Thanks, Issac

Dear all, Which options should I use when running the configure script and/or which changes should I make to Makeconf to build the binary for R-1.9.0 but using only statically linked libraries ? I need to build a binary that is portable between several different Linux (RedHat) distributions. Thanks in advance for your help, Melanie -- http://recherche-en-danger.apinc.org

Hi All, I have a greyscale image that I am reading in through RGDAL and placing in a pixmap object. As an example use the logo.jpg file that comes with the RGDAL package: #Read the file logo <- system.file("pictures/logo.jpg", package="rgdal")[1] x <- new("GDALReadOnlyDataset", logo) #Create the pixmap object xGrey <- getPixmapGDAL(x) Now I would

Hello, I am having trouble installing the package playwith on the latest Mint "helena", running R version 2.10.1 (2009-12-14). I suspect it has to do with the GTK library but as far as I can tell there is nothing wrong with it. Any help extremely appreciated.

Dear list, in R under wheezy the following error occurs: > library(cairoDevice) > Cairo() Error in Cairo() : Graphics API version mismatch It seems to be Debian-specific, as I tried the same under OpenSUSE 11.3 and it worked. I tried installing cairoDevice via `apt-get install r-cran-cairodevice' and with `install.packages("cairoDevice")' in R (without any
