Philip,
1) right now, tillage is being defined as a numeric vector and then
being coerced into a factor. So, try defining tillage in this way:
tillage - factor(rep(c(1,-1), each = 6, times = 5), levels=c(1,-1))
2) Why do you want to do this?
I hope this helps,

I see you are quite correct that IEEE_754 is defined in Rconfig.h on
MacOS X. However, I was building against a standalone libRmath v1.9.1.
So I was including Rmath.h only and IEEE_754 was not defined. The
result was that I got R_IsNaNorNA in the preprocessed source.
I finally found it.
