My apologies for the incorrect information. You can install the packages in the TaskViews with ctv package. I can see some problems when I try to install the MachineLearning core packages, but this may be due to the fact that I am "ahead of the curve". My R 3.0.0 beta installation under MacOS 10.6.8  already had most if not all of those packages installed but they were at higher version numbers than the ctv installation was requesting from the binary repository.

Got limited success (two packages installed) but several errors relating to 'missing packages' I think because there was a mismatch for ctv's requests for 3.0.0 beta with this command:

install.packages("ctv")
library(ctv)
install.views("MachineLearning", coreOnly = TRUE)

This did run without error:

install.views("MachineLearning", coreOnly = TRUE, type="source")

( Probably needs the XCode to be properly installed if on a Mac or RTools if on Windows.)
