Log message:
Update to 1.6.7

Upstream changes:
Changes in version 1.6-7

    fix some bug in handling weights in svm.default

Changes in version 1.6-6

    fix numeric issue in classAgreement()

    add functions from recommended packages to NAMESPACE

    fix bug in svm.default (incorrect handling of subset= argument)

    fix bug in predict.svm (new data with NA in response got removed)

    residuals are now correctly computed for regression in case of scaled data

Changes in version 1.6-5

    hamming.distance() no longer converts input to binary

    tune() now uses mean() to aggregate error measures from cross-fold replications

Changes in version 1.6-4

    remove library("SparseM") statements in code, use namespace \ 
semantics instead

    Fix memory leak and uninitialized read error in write.svm()

    add warning in predict.svm() if probabilities should be predicted, but the \ 
model was not trained with probability = TRUE

    add eps to laplace smoothing in predict.naiveBayes() to account for \ 
close-zero probabilities also.

    use R's random number generator for cross-validation and probability \ 
computation instead of the system one.

Changes in version 1.6-3

    remove require() statements and dependency on stats

Changes in version 1.6-2

    vignettes moved to vignettes folder.

    libsvm upgrade to version 3.17, getting rid of stdout and stderr

Log message:
Update to 1.6.1

Upstream changes:
Changes in version 1.6-1

write.matrix.csr() now accepts a fac argument similar to read.matrix.csr(), \ 
writing factor levels instead of the numeric codes.

naiveBayes() uses a numerically more stable formula for calculating the \ 
a-posterior probabilities.

predict.naiveBayes() now accepts data with predictors in an order different from \ 
the training data, and also ignores variables not in the model (especially the \ 
response variable).

svm() checks whether parameters which are passed to the C-code are set to NULL \ 
to avoid segfaults.

Log message:
Changes 2.11.1:

* R CMD INSTALL checks if dependent packages are available early on
* in the installation of source packages, thereby giving clearer
  error messages.
* R CMD INSTALL --build now names the file in the format used
  for Mac OS X binary files on that platform.
* BIC() in package stats4 now also works with multiple fitted models,
  analogously to AIC().
* Use of file extension .C for C++ code in packages is now
  deprecated: it has caused problems for some 'make's on
  case-insensitive file systems (although it currently works
  with the recommended toolkits).
* The C function mkCharLenCE now no longer reads past 'len' bytes
  (unlikely to be a problem except in user code).
* On systems without any default LD_LIBRARY_PATH (not even
  /usr/local/lib), [DY]LIB_LIBRARY_PATH is now set without a trailing colon.
* More efficient utf8ToInt() on long multi-byte strings with
  many multi-byte characters.
* aggregate.ts() gave platform-depedent results due to rounding
  error for ndeltat != 1.
* package.skeleton() sometimes failed to fix filenames for .R or
  .Rd files to start with an alphanumeric.
