Is this possible?

Dear Achim,
I suspect that the problem, involving a fifth-degree raw polynomial, is
very ill-conditioned, and that the computation in linear.hypothesis()
fails because it is not as stable as lm() and summary.lm(). (BTW, one

No you can not pass an address to a function. If you want to change
the value of something, then return it as a value and assign it to the

I had a question about the basic power functions in R.
For example from the R console I enter:
-1 ^ 2
[1] -1
but also
-1^3
[1] -1
-0.1^2
[1] -0.01
Normally pow(-1, 2) return either -Infinity or NaN. Has R taken over the math
functions? If so I would think that -1^2 is 1 not -1 and -0.1^2

Watch the operator precedences. In R (and many other languages)
-1^2 == -(1^2) == -1
Perhaps you intended:
