Sporadic errors when training models using CARET
...inear model using the "caret" package
(see code below). Using the same data, without changing any setting,
sometimes it constructs the model successfully, and sometimes I get an index
out of bounds error. Is this unexpected behaviour? I would appreciate any
insights this issue.
Thanks.

Specify feature weights in model prediction (CARET)
Using the 'CARET' package, is it possible to specify weights for features
used in model prediction? And for the 'knn' implementation, is there a way
to choose a distance metric (i.e. Mahalanobis distance)?
Thanks,
