[R] Test if beta is different from something other than 0

[John Fox]

Dear Corey,

The linear.hypothesis function in the car package will test any linear 
hypothesis. But the standard summary output for a linear model gives you 
the coefficient, its standard error, and the residual df, so why not just 
compute your own t, and use pt to get the p-value?
