I would like to deprecate La.eigen.  It is used in a few packages
(ade4, fpc, gss, mvtnorm and smoothSurv on CRAN), but only in usages where 
replacing `La.eigen' by `eigen' would call exactly the same code.

The reason for wanting to deprecate it is that little-used interfaces tend
to get overlooked, e.g. PR#5406, a report on eigen, needed to be applied
to La.eigen as well.  We have also fixed NaNs issues in eigen but not

Does anyone have code that uses the extra features of eigen?
