I am trying to run an R script to create a .png file containing a tree map on a headless Linux server using Xvfb. When I try to run tmPlot, I get the following errors and warnings: Error in grid.Call(L_textBounds, as.graphicsAnnot(x$label), x$x, x$y, : X11 font -adobe-helvetica-%s-%s-*-*-%d-*-*-*-*-*-*-*, face 1 at size 9 could not be loaded Calls: tmPlot ... <Anonymous> ->

Hello, When launching R from a script, when queried it reports the following capabilities as false: jpeg, png, x11 and cledit. When R is run from a terminal session, all of these capabilities are reported true. R is running on FC4. As the purpose of this script is to output the png file to a browser, it is unable to complete because of this. Any ideas are appreciated. We have an identical

Dear R-help I want to display an image file in a new plot frame. SVG is my preferred format, but I can also consider PNG, GIF, JPEG, TIFF, and PPM (from ImageMagick). By way of background (although not material to this posting), the image file is generated by a call to 'dot' (part of the 'Graphviz' suite) after the required .dot file has been produced using hand-crafted R code.

Dear Colleagues, We are attempting to create trees using R with our Ruby on Rails application. However, we are running into a problem involving the creation of the graphic. We would like them to be in either jpg or png format so that users can save, but due to a lack of control over our sever we are unable to start X11 server. Is there a way to create these images without using X11 server?

Dear all, I am trying to create a web interface using Perl-CGI to call R plots and to display them. The following codes works perfectly fine when I copy and paste into the console directly or if I save it into script.file and then R --no-save < script.file producing the graphs. jpeg("graph.jpeg", width=400, height=400) plot(rnorm(100)) dev.off() Now, I put the line system("R

Hi I have seen a few posts to this list regarding problems accessing the x11() device over cgi - namely, when trying to create a graphic using the jpeg() function, everything is fine from the command line but it won't work over cgi, producing the error: "Unable to open connection to X11 display" Has anyone actually solved this particular problem satisfactorily? Please reply

Hey, I'm generating a .jpeg file for a web application passing parameters to R via cgi. R gets the parameters by using commandArgs, which are passed to a variable named j and z j<-commandArgs()[3] z<-commandArgs()[4] Later I want to use the characters strings of the argument which the variables are holding for my filename, e.g.: jpeg(file="d:/data/images/jz.jpeg",...)

Hallo R-experts, I produced a R graphic with the help of the following commands: plot(0:4,0:4, type = "n", xlab = "X-Werte", ylab = "Y-Werte") points(rnorm(100), rnorm(100), col = "black") locator(2, type= "l") locator(2, type = "l", col = "red") I could display this graphic by using windows() before entering those commands.

Hi everyone, I am trying to make some publication-quality plots for use in Microsoft Word, but I am having trouble creating high-quality plots that are supported by Microsoft Word. If I use the R plot function to create the figure, the lines are jagged, and the picture is not of high quality (same with JPEG(), TIFF(), and PNG() functions). I have tried using the Cairo package, but it distorts

Hi there, Does anybody have experience in running jpeg device using xvfb-run on linux? I've been having sporadic problem with: /usr/X11/bin/xvfb-run /usr/bin/R --no-save < Rinput.txt, with error saying: error in X11 connection. Especially when I run it from a perl script. Is there a better way of doing this? or how can I fix the problem. Thanks in advance! David [[alternative HTML

Is it possible to produce the same graphic in different formats in one shot? Now if I want to produce the same graphic in pdf, ps and jpeg I run the producing code, but I change the graphic device, and I choose successively : pdf(...) ps(...) jpeg(...) So in this case I run the same code 3 times, or I have to choose a format and use converters... Is it possible to produce the 3 graphics in once

Hi I have recently installed and implemented Xvfb (X virtual frame buffer) so that I can create jpegs using R over CGI (SUSE Linux 8.1 and Apache 1.3). I have noticed that in order to do this, a file (Rplots.ps) is created in my cgi-bin directory everytime a cgi script is run. This could cause problems though as I have a multi-user system where it is possible that two different users will run

What is the easiest way to convert a webpage into a jpg or png file? I've seen several programs that can do various conversions, but nothing open source that can do it in a single conversion. Just wondering if anyone on the list has suggestions for something I can put into a script to convert a webpage into a file I can use with my screensaver. c

Hi a short question is there a way to generate jpeg's etc. in BATCH mode ? The following example does not work in BATCH: I have a file called Rgraph.in: *rsy at puffin*[15:11][~][57]> cat Rgraph.in jpeg("/tmp/my.jpg") hist(runif(10000)) dev.off() *rsy at puffin*[15:11][~][58]> *rsy at puffin*[15:09][~][55]> R BATCH Rgraph.in OUT 4.120u 0.160s 0:05.17 82.7% 0+0k

What is the simplest (namely: minimum number of libraries or conflicts) way to fill a polygon with a pattern? For example, suppose I have (in a graphic file, like a jpeg) the drawing of an "X". Then I fill a polygon (like a triangle) with this pattern, and get something like: X XXX XXXXX XXXXXXX (where the border "X"s could be truncated). I searched the rimage

Hi all, Although R seems to have jpeg() and png() functions that converts data into jpeg and png formated files, it doesn't have functions the other way around. Does one of R contributed packages have gif, jpeg and png image readers?

Hi all, I am have an R script that makes many plots, and I would like to string them into a movie file. To do that I have to save all of my plots as jpegs or gifs. I don't want to go through all of my plots and save them by hand though. Is there a way to automate saving the plots as a gif or a jpeg so I can string them into a movie? Thanks in advance Matt Oliver

I want to invoke R on a Linux Web server from Java, in order to analyse data in ways that would take too long to code, and run too slowly, in Java. In particular, to do correspondence analyses. To this end, I've installed R version 2.15.0 on my Web host's x86_64 GNU/Linux machine, and tried using package "ca" to run the "author" example of correspondence analysis
