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.
* 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.
