Hello,

	I just released a Graphics Device for R >= 1.4 which outputs w3 compliant 
SVG.  I Have also created a Java 1.1 applet which can render and manipulate 
the SVG generated from the graphics device.  

Please visit http://www.darkridge.com/~jake/RSvg/ for more info

Thanks,

(Win2000 / R.1.6.1)

...neverthless the  *.svg is written correctly.

Yeah I got the same.

I'm confused because it works fine in Linux.

I'm registering the device properly as fas as I can tell.

Can a core developer take a look and tell me what I'm doing wrong.  
The code is at the bottom of devSVG.c

Thanks,

Jake

Using undocumented non-public entry points in the R internals.  The
traceback is (whyever do people not report this basic information: see the
rw-FAQ for how?)

Call stack:
0048241B  R.dll:0048241B  free
004CA292  R.dll:004CA292  GEdestroyDevDesc
004F10F6  R.dll:004F10F6  Rf_selectDevice
0051B1FE  R.dll:0051B1FE  do_devoff
005049B4  R.dll:005049B4  do_internal
...

so the R graphics internals are calling R's internal free on memory
allocated by your device, which allocated the memory from msvcrt.dll and
not from the internal malloc.

Solution: build in the source tree of R and add -lRm to Makevars
(and you might as well have configure.win and Makevars.win whilst you are
at it).  That gives you access to R's internal malloc.

This is fixed.  It no longer crashes on Win32. Sorry about that.

Grab new version from http://www.darkridge.com/~jake/RSvg

It should be on CRAN soon.
