Log message:
Update all R packages to canonical form.

The canonical form [1] of an R package Makefile includes the

- The first stanza includes R_PKGNAME, R_PKGVER, PKGREVISION (as
  needed), and CATEGORIES.

- HOMEPAGE is not present but defined in math/R/Makefile.extension to
  refer to the CRAN web page describing the package.  Other relevant
  web pages are often linked from there via the URL field.

This updates all current R packages to this form, which will make
regular updates _much_ easier, especially using pkgtools/R2pkg.

Log message:
Remove MASTER_SITES= from individual R package Makefiles.

Each R package should include ../../math/R/Makefile.extension, which also
defines MASTER_SITES.  Consequently, it is redundant for the individual
packages to do the same.  Package-specific definitions also prevent
redefining MASTER_SITES in a single common place.

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.
