[R] Cp -Inf

[Stephen Sefick]

Hello All:

I am using the leaps package on scale and centered data for an 
exhaustive search.  There are Cp values of -Inf being returned for all 
models.  I was going to look at the source before contacting the list, 
but it has been a while since I have looked under the hood.  There are 
.rdb and .rdx files where I expected the source files to be.  I am sure 
that I have over looked something.  I can provide data and code if it is 
needed.
