Actually it seems that it should be the way to go: I just noticed under the

Hi.
First of all, thanks to all who have replied.

EViews (econometrics program) doesn't have the same opinion:
Wald test on my real model (edited):
* H0: B3/B2 = 0 -> F-stat = 37.82497
* H0: B3 = 0-> F-stat = 16.31689

In your first example I get an error:

The switch function does not work the way you are expecting it to.
Read help("switch") and read the introduction to R that comes with R.
You probably want to use the output of menu() to ex
