[R] Xtable giving an interesting problem

[Shawn Way]

I'm using the current version of xtable for 1.9.0 and I have an
interesting error:

Error in match.names(clabs, names(xi)) : names don't match previous
names:
	 F value, Pr(>F)
In addition: Warning message: 
longer object length
	is not a multiple of shorter object length in: clabs == nmi 

This is produced in the following manner:

>data.trans <- data.frame(ref=rep(c(3.995,20.003),2),
                              actual=c(.1,100.3,.1,100.3),
                              level=gl(2,1))
 
>parameters <- data.frame(trans.range=c(0,100), trans.output=c(4,20),
                          ref.error=c(.0074))
>a <- lm(trans.range~trans.output,data=parameters)
>pred <- data.frame(trans.output=data.trans$actual)
>data.trans$cor <- predict(a,pred)
>fit.trans <- lm(cor~ref,data.trans)
>fit.trans.aov <- aov(cor~ref+Error(level),data.trans)
>fit.trans

Call:
lm(formula = cor ~ ref, data = data.trans)

Coefficients:
(Intercept)          ref  
    -180.66        39.12

Call:
aov(formula = cor ~ ref + Error(level), data = data.trans)

Any ideas?
