Subject: [Rd] knnFinder package
Message-ID: <4790C38B.5000307@msu.edu>

Hello all,
The ann() function in the yaImpute package provides a more full featured 
interface to the same underlying approximate nearest neighbor library 
(http://www.cs.umd.edu/~mount/ANN) that is called by the nn() function 
in knnFinder. knnFinder is actually calling an older (defunct) version 
of the ANN library which was known to cause some segmentation faults.

I would be willing to adopt knnFinder, but it is now redundant with the 
functions offered in yaImpute. But first a question -- Should we 
maintain existing packages that have been superseded by other packages? 
If so, then I'll adopt knnFinder, but if not then I suggest letting it go.

Kind regards-
Andy
