Hi All, I've started work on a MetaPost device driver (please don't hold your breath). I've copied the XFig driver and renamed everything and this works, I can open the new metapost() and it works exactly like the xfig driver. Now all I have to do is the actual work! Just one question. There is a magic number in ExtEntries as follows: static const R_ExternalMethodDef ExtEntries[] =

Hi, 1. I started work on a metapost graphics driver a week or so ago and it is gradually taking shape. I'm building up my own test cases into a script as I go, but figured you may have a "canonical testing script" of cases a driver must handle? 2. The clipping function looks like being a tricky problem. It seems to me that the callers of the driver assume that clipping affects all

Hi, I know the R can make eps output. But metapost sees to be an even better choice for me. I've been using gnuplot for a while, it seems it has excellent support with its metapost latex terminal. So I can insert any latex equation in the figure. Meanwhile, I can make the font in the figure will be consistent with font used in the main text. I searched R help, but I can not find metapost

Hi, I read the 2000 thread on a MetaPost device in R. If I understand correctly, the main problem with the concept is that R wants the device driver to give back information on the size of strings/labels. To the bet of my knowledge, MetaPost _does_ make it possible to measure the bounding box of text (see section 7.3: Measuring text in the MetaPost manual). For example, one could get the size of

Hi all, By default, MetaPost passes all text through TeX. This has the advantage of allowing essentially any TeX symbols in titles and labels. It give us, who use the multibyte character in ordinary communication, much convenience. Gnuplot has fulfilled this function, and it give me a deep impression for I could use Chinese character in plots with a minor modification to the MetaPost file. I

I would like to know if a MetaPost device is available or in the plans. A search MetaPost in the documents and list archives did not turn up anything. [I would prefer to use MetaPost when the graphics is to be included in a document that I want in both hard-copy and in pdf formats.] If not, how easy/hard is it to add a new device to R? I caouln't see anything about adding devices in the

Dear list, Tadashi Kadowaki has developed a pdf device package that allows to add hyperlinks and popups to (currently) text, mtext and rect calls. The package passes R CMD check (minor warnings) and compiles on MacOS X and GNU/Linux, but we do not succeed in building the package for Windows. The current version of the package can be checked out as svn checkout

I followed the suggestions at http://developer.r-project.org/SVNtips.html to check out an anonymous copy of the development branch of R, but so far I have been unable to figure out an analogous way to track the development branch of the recommended packages. (I'm assuming they actually live somewhere on the same SVN server, which might not be true ...) Any ideas (including pointing out the

Hi, This may just be an inconsistency between terminal drivers, rather than a proper bug. If the main title of a plot is too wide to all fit on the plot, the X11 driver prints as much of the title as it can, but the postscript driver totally ignores the title. Here's a simple example: % R > plot(runif(1000), main="a long xxxxxxxxxxxx title") >

Documentation and other bugs with postscript(): 1. This code crashes R (it asks for a font that isn't there): postscript() plot(0:1,0:1) text(0.5,0.5,'crash',font=6) The bug appears to be in the FixupFont routine in plot.c; on line 236, it checks that the font number is in the range 1..32. Later this crashes PostScriptStringWidth in devPS.c, because only fonts numbered 1..5

Hello, The current xfig device lacks the functionality to set the textspecial flag and use the defaultfont in xfig. This is necessary when you want to export to xfig and use interpreted text (e.g., $ \frac{1}{e}$ gets interpreted by latex). The attached patch adds this functionality. Why would you like to do this? - Use math in labels (e.g., name your variables $r_{xy}$, do a

Except for the ability to perform circular recalculation, I believe that the closest programming analogy to a spreadsheet is a functional programming language.

Full_Name: Jussi Jousimo Version: 2.1.1 OS: Linux Submission from: (NULL) (193.167.195.60) R 2.1.1 crashes when it is trying to write a file with the postscript driver to a directory, where the user has no permission to write. For example, postscript("foo.ps") gives an error message: *** glibc detected *** free(): invalid pointer: 0x08a469b0 ***. The problem is at the PSDeviceDriver

Hi all, I downloaded R-devel as explicited in https://developer.r-project.org/SVNtips.html Then, I tried to install it through instructions in https://cran.r-project.org/doc/manuals/r-devel/R-admin.html#Installation (taking into account also https://stat.ethz.ch/pipermail/r-devel/2016-May/072777.html) So: export REPOS=https://svn.r-project.org/R export RTOP=~ #adjust as necessary cd $RTOP svn co

Hi, I am finding the recently added [1] functionality of embedding raster images into plots on R devices very useful! Thanks to Paul Murrell and others for providing that. I noted that in https://svn.r-project.org/R/trunk/src/library/grDevices/src/devPS.c a macro is defined: #define MAX_RASTERS 64, and consequently, I get Error in grid.Call.graphics("L_raster", x$raster, x$x, x$y,
