similar to: Draw a rectangle on top of an image using RGtk2?

Dear all, I try to use RGtk2:::gdkColorToString, but it throws an error: Error in .RGtkCall("S_gdk_color_to_string", object, PACKAGE = "RGtk2") : gdk_color_to_string exists only in Gdk >= 2.12.0 I know what it means, but don't know to solve this problem because I don't know where I can download the referred gdk library. Any information? Thank you. -- HUANG

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

Does someone here know of a way to display images in R that isn't slow? Here are the things I've tried so far: library(rimage) i<-read.jpeg('foo.jpg') plot(i) # very slow library(pixmap) i <- read.pnm('foo.pnm') plot(i) # also slow chans <- getChannels(i) image(chans[,,1]) # this is slow too I also tried using library(cairoDevice) but it only makes everything

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

Hi UseRs, I recently started working with the RGtk2 library. The documentation is comprehensive and I've tried learning from the examples in most Gtk tutorials (which have C code). This is a little problematic, but has helped quite a bit in getting me started. I would like to create a GUI for file selection, which then displays the column names from the selected file, and provides the user

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

Dear all, I want to set tool-tips for a gtkButton. I use the following code which works under Windows. However, it doesn't work under Linux. Any hints? Thanks. library(RGtk2) b<-gtkButtonNewWithLabel("OK") gtkTooltips()$setTip(b,"Memo for a Button.") gw <- gtkWindow(show=F) gw$Add(b) gw$Show() > sessionInfo() R version 2.8.0 Patched (2008-12-10 r47137)

I want to write a function mimic the function of select.list(), here is my preliminary version. select <- function(x,multiple=TRUE,...){ ans<-new.env() g <- gwindow(title=title,wid=200,heigh=500) x1<-ggroup(FALSE,con=g) x2<-gtable(x,multiple=multiple,con=x1,expand=TRUE) gbutton("OK",con=x1,handler=function(h,...){ value <- svalue(x2) if (length(value)==0)

Dear List, I would like to ask about package RGtk2 with which I have a problem. I will very much appreciate if somebody could tell me what I need to do. I need to install a package scdMicro and it depends on gWidgetsRGtk2. I am working on MAC, version 10.5.8. When I try to load gWidgetsRGtk2 (or RGtk2), it asks me: "Instal GTK+?" I installed Gtk+ from CRAN, and added a path: export

Hi, I am wondering if some experienced users would help put the ready-to-run code of the examples in the manuals. It would help new users learn R faster by putting all the examples in an ready-to-run R script file. Can somebody help do so sometime and post the code along with the pdf manuals? http://cran.r-project.org/manuals.html Regards, Peng

Dear r heper, How can I change the strip text, for example (16,23] in the following example, to other more informative text such as "high level" on the fly? library(effects) Cowles$ex2 <- cut(Cowles$extraversion,3) mod.cowles <- glm(volunteer ~ sex+neuroticism*ex2,data=Cowles, family=binomial) eff.cowles <- allEffects(mod.cowles) plot(eff.cowles,

I believe this posting is placed, and I take the liberty to re-direct to the r-help mailing list.

It turns out that when I use GUI (file-change dir) to set the working directory, R will crash. If I use setwd() instead, the example runs well.

I installed version 2.10.9-1 of RGtk2, but when I tried to load it I received the following message: > local({pkg <- select.list(sort(.packages(all.available = TRUE))) + if(nchar(pkg)) library(pkg, character.only=TRUE)}) Error in dyn.load(x, as.logical(local), as.logical(now)) : unable to load shared library 'C:/Programmi/R/R-2.5.0/library/RGtk2/libs/RGtk2.dll':

Dear all, I try to show a subset of coefficients in my presentation. It seems that a "standard" table is not a good way to go. I found figure 9 (page 9) in this file ( http://www.destatis.de/jetspeed/portal/cms/Sites/destatis/Internet/DE/Content/Wissenschaftsforum/Kolloquien/VisualisierungModellierung__Beitrag,property=file.pdf ) looks pretty good. I wonder if there is any function for

The new 2.10.x series of the RGtk2 package has recently become available on CRAN. RGtk2 is a package for creating graphical user interfaces (GUI's) in R and is similar in purpose to the tcltk package. RGtk2 binds to and enables the extension of the GTK+ user interface library, as well as several other libraries that are integrated with GTK+. The gWidgetsRGtk2 package provides an RGtk2
