Lucerne
...inux services and patches wine to use these rather than emulate them. Anyone used, had success with this? Worthwhile? Patching kernels, while not for all newbies, is fairly quick and hopefully painless, at least in Debian. Patching wine is a big job. Since any wine must test on startup whether Lucerne patches and drivers are there, it might be nice if their thing got incorporated into mainline winery. Got 'em, use 'em, or else run just like now.

Packages for Learning Algorithm Independent Branch and Bound for Feature Selection
I am looking for packages that can run a branch-and-bound algorithm to maximize a distance measure (such as Bhattacharyya or Mahalanobis) on a set of features. I would like this to be learning algorithm independent, so that the method just looks at the features, and selects the subset of a user-defined size that maximizes a distance criteria such as those stated above. Can anyone give some

Control number of assets in resulting portfolio with optimizations using package fPortfolio
Dear All, I am using package fPortfolio to run minimum variance portfolio optimizations in R. I already know how to set portfolioSpecs, portfolio objects and constraints. Unfortunately I am not able to set the following type of constraints. I have a timeSeries object with returns data for roughly 1.5k assets for 261 subperiods (workingdays) and want to compute the global minimum variance

How can I find nonstandard or control characters in a large file?
I have a humongous csv file containing census data, far too big to read into RAM. I have been trying to extract individual columns from this file using the colbycol package. This works for certain subsets of the columns, but not for others. I have not yet been able to precisely identify the problem columns, as there are 731 columns and running colbycol on the file on my old slow machine takes

Basic astronomy package recommendation wanted.
Given - UTC timestamp - a location (latitude,longitude,elevation) I want to know - the sun angles - the moon angles - the phase of the moon. I looked on CRAN for astronomy, but didn't notice anything that seems to offer what I want. I could try coding these functions myself, but "if you didn't write it you didn't wrong it".
