The following are now on CRAN:
KernSmooth: version 2.2 of the code for Wand & Jones book on kernel smoothing.
logspline: spline fits to log denisites, with automatic choice of smoothing.
ppr: projection pursuit regression.
rpart: recursive partitioning (CART-like)
VR: Venables & Ripley libraries 5.3pl021 for 0.62.1
and in the devel section
tree: a clone of tree, prune.tree, cv.tree ...
which is fully operational but not much documented. Use your V&R2!
You can find out about KernSmooth, logspline, ppr and rpart in the
on-line statistics complements to Venables & Ripley at
The final release of the VR libraries is yet to come: it will follow
the bug-fixes in 0.62.2. If you really want to experiment, the current
version will be at http://www.stats.ox.ac.uk/pub/R, but do use this with
the latest R-release.tar.gz or R-snapshot.tar.gz.
