[R] Q: Problems with eigen() vs. svd()

[Paul Gilbert]

As I recall, eigen() in Splus did only work for symmetric matrices sometime in
the last millenium. I believe it changed around 1994. I don't think R had
eigen() until around 1996, and I believe it may not have worked with
non-symmetric matrices at first, but that changed very quickly. History buffs
please correct me. I work with time series but I'm not good at remembering
dates.
