Hi
I am having difficulty with eigen() on R-devel_2006-01-05.tar.gz
Specifically, in R-2.2.0 I get expected behaviour:
> eigen(matrix(1:100,10,10),FALSE,TRUE)$values
[1] 5.208398e+02+0.000000e+00i -1.583980e+01+0.000000e+00i
[3] -4.805412e-15+0.000000e+00i 1.347691e-15+4.487511e-15i
[5] 1.347691e-15-4.487511e-15i -4.269863e-16+0.000000e+00i
[7] 1.364748e-16+0.000000e+00i -1.269735e-16+0.000000e+00i
[9] -1.878758e-18+5.031259e-17i -1.878758e-18-5.031259e-17i

The same command gives different results in the development version:
> eigen(matrix(1:100,10,10),FALSE,TRUE)$values
[1] 3.903094e-118 -3.903094e-118 -2.610848e-312 -2.995687e-313

Note the strange magnitude of the output.

I need this to work because one of my packages fails under R-devel
