Dear Group, I'm trying to build a set of new graphic device drivers. I use the devNull example a a beginning point: $ R CMD SHLIB devNull.c gcc -shared -L/usr/local/lib -o devNull.so devNull.o (everything works OK) $ R CMD SHLIB devNull.cpp g++ -shared -L/usr/local/lib -o devNull.so devNull.o (everything works OK) The difficulties start when trying to compile manually. I compile the

Hi all, i'm trying to install JGR on linux (see bottom), but it runs into errors. The bottom of the sequence below shows "JavaJD could not be found" Any suggestion, please? $ sudo apt-get install sun-java6-jdk $ sudo update-alternatives --config java There are 5 alternatives which provide `java'.

I want to use contourLines() to get contour line coordinate vectors, but I don't want to make a plot. However contourLines() insists on opening a graphics device.

R 2.1.0/src/include from 2005/04/18 download Naming inconsistent for guards as well but that's pedantic. Simple convention: file <foo.h> #ifndef R_FOO_H file <R_ext/bar.h> #ifndef R_EXT_BAR_H Missing guards: <IOStuff.h> <Internal.h> <Parse.h> <R_ext/GraphicsBase.h> <R_ext/GraphicsDevice.h> <R_ext/GraphicsEngine.h>

Hi r72261 in r-devel has modified the graphics device API and bumped R_GE_version in GraphicsEngine.h (to satisfy PR 16951). This means that ... (i) third-party graphics device packages need to be reinstalled. (ii) third-party graphics device packages will ideally need a new version for r-devel. (iii) any packages that make use of getGraphicsEvent() should test against r-devel (and let me

Since R 2.5.0 it has been possible to declare the encodings of character strings (at the level of individual elements of a character vector). As a reminder, here is the announcement in NEWS o R now attempts to keep track of character strings which are known to be in Latin-1 or UTF-8 and print or plot them appropriately in other locales. This is primarily intended to make it possible

Hi This is for developers of extension packages that provide extra *graphics devices* for R. In the *development* version of R, support has been added to the graphics engine for rendering polygons with holes (e.g., maps with lakes with islands ...). The API change is a new dev_Path() function for graphics devices. The R_GE_version constant (in GraphicsEngine.h) has been bumped up to 8 as a

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

Hi This is for developers of extension packages that provide extra *graphics devices* for R. In the *development* version of R, support has been added to the graphics engine for sending raster images (bitmaps) to a graphics device. This consists mainly of two new device functions: dev_Raster() and dev_Cap(). The R_GE_version constant (in GraphicsEngine.h) has been bumped up to 6 as a

I've rolled up R-2.6.0.tar.gz a short while ago. This is a development release which contains a number of new features. In particular, the handling of data with a large number of identical strings should be more memory-efficient. Also, a number of mostly minor bugs have been fixed. See the full list of changes below. You can get it (later today) from

Hi, I am happy to announce that I finished the translation of almost all LGPL'ed R headerfiles to Delphi. As a test I did several demos which basically contain delphized versions of all the examples of chapter 5 in "Writing R Extensions". Please have a look in the attachments for details (DemosAndHeaders.txt), more information (Readme.txt) and an example of how it looks

I have a continuous loop running in an external library that I am calling from C (R API). This loop is processing events in real time with the possibility of significant lag between events. When processing an event, I can make use of R_CheckUserInterrupt, but while the external library code is waiting on a new event, I don't have an opportunity to call this - my entry points are only on

I've been testing plotmath. But I'm getting some funny output one one computer. The problem is that characters are 'jumbled' and overstrike when symbols are introduced. Sample code: mu <- 440.0 sigma <- 12.5 myx <- seq( mu - 4*sigma, mu+ 4*sigma, length.out=500) myDensity <- dnorm(myx,mean=mu,sd=sigma) # Here's one way to retrieve the values of mu and sigma and

Hi! When inserting R plots into a document using odfWeave, I fought for a while to get Lattice plots use the same text size as base plots. I eventually discovered that specifying a point size via e.g. svg(pointsize=10) has no effect on Lattice plots. One needs to adjust the size manually via: trellis.par.set(fontsize=list(text=10, points=8)) This is also developed for both Lattice and ggplot2 by

I have: module MySpike extend ActiveSupport::Concern included do class_attribute :foobar, instance_writer: true end end But, I want to be able to override the class attribute writer and/or instance writer method to do something when the attribute is set via self.foobar = true before or after calling super to set the attribute. Unfortunately, I can''t find a clean way

Thank's !! I'll try during the week, and will let you know if all is fine ;) Le mar. 10 juil. 2018 à 07:36, Olly Betts <olly at survex.com> a écrit : > On Mon, Jul 09, 2018 at 10:29:18AM +0100, Olly Betts wrote: > > The attached patch reset this cursor each time commit() is called, and > > that fixes my C++ reproducer, though I think this ought to work as-is >
