NA in eigen()
Hi,
I am using eigen to get an eigen decomposition of a square, symmetric
matrix. For some reason, I am getting a column in my eigen vectors (the
52nd column out of 601) that is a column of all NAs. I am using the option,
symmetric=T for eigen. I just discovered that I do not get this behavior
when I use the option EISPACK=T. With EISPACK=T, the 52nd eigenvector is
(up to rounding error) a vector of all zeros except for -0.6714
and +0.6714...

Difficult with round() function
...ely (I am sure there is a
far more elegant way to regrid data in R) or a simple fix for this rounding
error.
Many thanks in advance,
Aaron
