[R] Sweave special characters problem

[Bunny, lautloscrew.com]

Thx everybody, 

finally I got it to go. I switched all three files (mysource.R, sweavetemplate.Rnw,invokeSweave.R) to UTF-8 encoding, switched the options() like suggested below and it just worked.

The error message is some strange mixture of german and english, so this what the error message is supposed to look like:
>> "Invalid multibyte character in Parser line 195" . Allan´s example works as a standalone, with his code I get the following error message. Maybe this is a mac problem ...

I tried getting that editor/system to work as an editing environment a year ago and formed the opinion that there were too many got-cha's in the specification of options and user environments. I gave up and went back to a less complex (and in my hands, less fragile) strategy. I would take your question to whatever support site is available for Sciviews-R. (I suppose it could be a Leopard vs Snow Leopard issue, but do not have the resources to investigate.)
