Package: R.matlab
=================

Version: 1.0.2 [2005-05-03]
o Now Matlab struct's are read into an R structure.
o BUG FIX: Reading empty struct:s (and cells) tried to read one 
  field because seq(0) and not seq(length=0) was used. Updated all
  occurances of this problem.
o Replaces package directory misc/ with two new directories 
  mat-files/ and externals/.

Version: 1.0.1 [2005-04-08]
o BUG FIX: readMat() failed to read some Matlab struct's because
  of a parsing error.
o BUG FIX: Internally in readMat() - in readMat5DataStructure() it 
  might be data readTag() returns a tag referering to a data block 
  of zero length (nbrOfBytes == 0). Now list(NULL) is returned in 
  this case.
o BUG FIX: The MatlabServer script did (indeed) not work with 
  Matlab v7; the wrong version was included.
  Thanks Patrick Drechsler, University of Wuerzburg for reporting
  the above two problems.
o Minor additions to help pages.

Version: 1.0 [2005-02-25]
o Moved to CRAN.

Version: 0.94 [2005-02-24]
o Updated the MatlabServer.m script to automatically set the Java
  classpath for Matlab v7 and higher. This will assure that
  InputStreamByteWrapper.class is found as long as it is in
  the same directory as the *.m script. Thanks Yichun Wei at 
  University of Southern California for suggesting this and
  also for suggesting additional help instructions.
o Added a Wishlist and an Acknowledgements section to "about".
o Added more information on how to start the Matlab server.

Version: 0.93 [2005-02-20]
o Added autoload("hasVarArgs") to 000.R.
o Updated the Matlab example to be more explicit about problems
  with Matlab$startServer() and Matlab v7. 

Version: 0.92 [2005-02-17]
o Package now passes R CMD check on R v2.1.0 devel without warnings.
o Added appendVarArgs=TRUE to setMethodS3(), which specifies that
  '...' should be added, if missing.
o Add argument '...' to all methods to make it even more consistent
  with any generic function. This is also done for a few methods
  in the R base packages.
o BUG FIX: readMat() would not read non-signed bytes correctly.

Version: 0.91 [2005-02-11]
o Package passes R CMD check on R v2.1.0 devel too.
o Moved the Java class from R.io to this package, since it is
  currently only used here. It is used for reading and writing 
  Java bytes, ints and (UTF) strings when communicating with Matlab.
o Updated description of package. Preparing for moving to CRAN.
o Added Rdoc comments to internal Verbose classes.

Version: 0.8 [2004-02-24]
o Added a setVerbose() method to the Matlab class, which allows the
  user to get details at various levels of the Matlab process.
o WORK AROUND: It sometimes happens that the reply from Matlab is not
  transferred "quick enough" and even if the connection should block we
  receive NULL giving an error. The work around for now is to try to
  read the answer again. The symptom was that an error in readResult()
  complain about "if (answer == 0)" where answer was of length 0.
o Added support for reading sparse matrices. Sparse matrices
  are expanded to regular matrices, which means that some may
  be too large to be loaded.
o BUG FIX: The header of MAT v4 files was not parsed correctly, 
  which made MAT v4 files unrecognized and assumed to be 
  MAT v5 files which in turn could not be read.
o BUG FIX: Used "sparce" instead of "sparse" in MOPT[4] tag (MAT v4),
  which most likely would generate an error for such structure.

Version: 0.7 [2003-12-02]
o BUG FIX: Introduced a bug that made files written with big endian
  not to work. The reason was that "<-" was used instead of "<<-"
  in one new method. I do not like "<<-", but that is how it works.

Version: 0.6 [2003-11-25]
o Created an readMat() that can read both MAT v4 and MAT v5 files.
  The MAT v4 reader was kindly provided by Andy Jacobson at the
  Princeton University. 
o writeMat() was created for consistency, but it does only support
  MAT version 5.
o Note that I have now choosen to rename readMAT() and writeMAT() 
  to readMat() and writeMat(), respectively. This is in line with
  the RCC, cf. readHtml() instead of readHTML(). If you really need
  readMAT() and writeMAT() you can easily write your own wrappers.

Version: 0.5 [2003-04-04]
o I forgot to remove some debug code that outputs information about
  the Description comment everytime a MAT file is read. Removed.

Version: 0.4 [2003-01-16]
o Now require(R.io) is loaded with the package and not when the first
  Matlab client/server method is called. The former approach was a little
  bit annoying.
o BUG FIX: The Matlab client/server implementation was broken due to 
  bugs introduced in the Java class of the R.io package. Correcting 
  these bugs made the Matlab part work again.

Version: 0.3 [2002-11-11]
o BUG FIX: readMAT() would not work because getBits() previously in
  package R.oo was removed. getBits() is no added as a local 
  function inside readMAT().
o Made all methods \keyword{internal}.

Version: 0.2 [2002-10-23]
o Upgraded to make use of Rx.oo.

Version: 0.1 [2002-09-03]
o Initial methods are readMAT() and writeMAT() for reading and
  writing Matlab MAT file structures.
o Initial class is Matlab, which provides static methods for
  communicating with running Matlab server.
o Package created.
