[R] Matlab import

Hallo,

I did the saving again without 'ascii' option but the import also did not work. I get the following error message:

> library(R.matlab)
> mats <- readMat("Z:/Software/R-Programme/test2.dat")
Fehler in list("readMat("Z:/Software/R-Programme/test2.dat")" = <environment>,  : 
        
[2007-04-10 14:57:52] Exception: Tag type not supported: miCOMPRESSED
  at throw(Exception(...))
  at throw.default("Tag type not supported: ", tag$type)
  at throw("Tag type not supported: ", tag$type)
  at readMat5DataElement(this)
  at readMat5(con, firstFourBytes = firstFourBytes, maxLength = maxLength)
  at readMat.default("Z:/Software/R-Programme/test2.dat")
  at readMat("Z:/Software/R-Programme/test2.dat")

Any further idea,
Corinna
