We have a setup in which we use PHP (with Geeklog as a CMS) as a front end to MySQL. We plan to use R for offering user driven and automated statistical analysis of some of the data we obtain. We'll be using the R interface to the MySQL database from omegahat (www.omegahat.org) for getting the data out of the database, but we were wondering if somebody tackled the problem of how to integrate

Thanks Frederick. Mark, if you have any examples to share, they would also be gratefully received.

Hi The current status is that I am keen for people to contribute some testing code (see https://bugs.r-project.org/bugzilla/show_bug.cgi?id=16951) There were also some getGraphicsEvent() changes/fixes suggested by Richard Bodewits (cc'ed), for which I am also seeking test code.

Hi Just taking a bit more of a look at this today (currently fixated on making sure I can build some good regression tests). The best thing you can do is to keep reminding me like this :) Paul On 09/12/16 11:19, frederik at ofb.net wrote: > Hi Paul, > > Thanks for your efforts.

Hi By the looks of it, you need to install Cairo graphics ... https://www.cairographics.org/download/ Paul On 13/10/17 15:48, John wrote: > Thanks, Paul.

I'm build with the usage of the tcltk/tcltk2 package a gui which is started with rscript.exe. At this gui the user is able to open and close plot windows. Now I'm looking for a way that a r function is called when a grDevices::windows window is closed. Is there a way to attach a callback function or so, which would be triggert if the user click at close of the grDevices::window? My

Hi You could also look at dev.capture(), depending on which screen device you are using.

How can I insert a vector image in svg or pdf format into a plot. Basically i need the equivalent of what the 'pixmap' package does for bitmap images. Cheers, Will Morris

Hi, I have been having issues producing plots in JPEG format, using type = "cairo" to get better anti-aliasing. When trying to set the physical size with units = "cm" or units = "mm", the width is set correctly but the height is not - it looks like the height is simply treated as pixels regardless of the 'units' argument. Example: x = 1:10 y = 2 * x

Hi all:I found some great demonstrations of interactive presentation graphics generated in R with the SVGAnnotation package, here:http://www.omegahat.org/SVGAnnotation/http://www.omegahat.org/SVGAnnotation/SVGAnnotationPaper/SVGAnnotationPaper.htmlI tried to install the package available at that website (it's not on CRAN) and am getting some pretty uninformative errors (see below). My best

Hi, I am editing a document for submission to the R-news newsletter, and in my article my Sweave code inserts a dynamically generated PDF report that my R program generates. However, when I insert the PDF using the following Sweave code: \newpage \includegraphics[scale=1.0]{\Sexpr{print(location)}} \newpage (in tex this looks like): \newpage \includegraphics[scale=1.0]{/home/arjun/sample.pdf}

Hi Taking a look at those patches is now on my todo list, so I may be in touch with both of you at some point to request some testing.

Hi, I tried to use boxplot function. I am following the ?boxplot and can change the whisker box width using lwd parameter. However, when outline=TRUE, the thickness of the circle of the outliers is not proportionally changed when I change the line width of the whisker box. There must be another parameter for that. Unfortunately I don't know. please help and thanks much in advance. --
