[R] An issue with White's test in Anova

[David Kaplan]

Hi all,

I'm running White's test to correct for non-constant error variance and 
I am using the Anova function in the package CAR.  My command structure is

 > Anova(scireg3, white.adjust="hc3")

where scireg3 is an object from lm.

I get the message

"Error in SS[i] <- SS.term(names[i]) : nothing to replace with"

What does this mean and how do I fix it.

Thanks in advance.

David
