unicode only works with a second one - R-help

Hi Greg and Paul,

I tried several things, but I did not succeed:

* I could not find the library(EBImage) on CRAN in Austria to open an
png image in R.

* I could not import the image via pixmap (read.pnm) as described on
http://wiki.r-project.org/rwiki/doku.php?id=tips:graphics-misc:translucency
because my GIMP cannot write pnm format.

* I could not manage use the 'grImport' package to trace the svg:

Fehler in readPicture("Aries.svg") :
  Version mismatch: RGML file needs to be recreated with PostScriptTrace()

* I gave up modifiying the svg code from wikipedia to make it an R
array (structure) as you greg described it above.

If you have any hint for me please let me know. I am willing to
contribute something to TeachingDemos (although I am not sure if this
is not a license problem as I trace the (public domain) images from
wikimedia.

Otherwise I am happy with the Hershey fonts so far.

It's in the Bioconductor repository.

Hi

Yep, you need to convert to PostScript (ImageMagick or InkScape ought to
do it) before you can import it.  See

for a thorough description of how the package works.
