A new version of e1071 has been released to CRAN which should be much
easier to install on a lot of platforms because reading/writing PNM
images has been moved to the pixmap package, hence there are no longer
dependencies on external libraries and no configure mechanism.

For the authors,
Fritz Leisch

**********************************************************

Changes in Version 1.2-0:

  o Added functions for bagged clustering, see help(bclust).

  o read.pnm() and write.pgm() have been removed from e1071, much
    improved versions can now be found in the new package pixmap.

  o Lots of documentation updates and bugfixes.

  o Support Vector Machine interface now upgraded to libsvm V. 2.31
    featuring:
    - Multi-Class Classification
    - weighting of classes for C-classification (for asymmetric sample sizes)
    - nu-regression
    - Formula Interface
    - k-fold cross-validation
    In addition, an introductory article is provided in directory
    `docs/' (svmdoc.pdf).

  o classAgreement now features an option to match factor levels

  o updated API design for the fuzzy clustering functions
    (cmeans, cshell, scaclust). Documentation updates and function
    name changes (cmeanscl -> cmeans, validity.measures -> fclustIndex)
