[R] openNLP package error

[Sascha Wolfer]

Hello list,

I seem to have a problem with the openNLP package, I'm actually stuck in 
the very beginning. Here's what I did:
 > install.packages("openNLP")
 > install.packages("openNLPmodels.de", repos = 
"http://datacube.wu.ac.at/", type = "source")

 > library(openNLPmodels.de)
 > library(openNLP)

So I installed the main package as well as the supplementary german 
model. Now, I try to use the "sentDetect" function:

 > s <- c("Das hier ist ein Satz. Und hier ist noch einer - sogar mit 
Gedankenstrich. Ist das nicht toll?")
 > sentDetect(s, language = "de", model = "openNLPmodels.de")

I get the following error message which I can't make any sense of:

Fehler in .jnew("opennlp/maxent/io/SuffixSensitiveGISModelReader", 
.jnew("java.io.File",  :
   java.io.FileNotFoundException: openNLPmodels.de (No such file or 
directory)

The model seems to have been installed just fine but there seems to be a 
directory missing. The documentation of openNLP doesn't mention anything 
like setting a particular working directory or something... also a 
Google search for this error didn't come up with anything useful.

Does anybody have a solution for this?

I'm on R 2.12.0 on Mac OS X 10.6.5

Thanks,
Sascha
