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 k...

Partly about new features and partly about old features that are not being used. R_exts/GraphicsEngine.h says /* * The current graphics engine (including graphics device) API version * MUST be integer * * This number should be bumped whenever there are changes to * GraphicsEngine.h or GraphicsDevice.h so that add-on packages * that compile against these headers (graphics systems such as...

...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 marker of this change. This means that, at a minimum, all graphics devices should be updated to provide dummy implementations of these new functions that just say the feature is not yet implemented (see for example the PicTeX and XFig devices in the 'grDevic...

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.

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 marker of this change.

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

Hi Ivan Can you please clarify what input files should be used with your proposed function?

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
