[R] summary.lm

[Roger D. Peng]

Is it possible you have a locally modified version of 
summary.lm() lying around.  Here are the first few lines of 
summary.lm() in R 1.9.0:

 > head(summary.lm)

1 function (object, correlation = FALSE, symbolic.cor = FALSE,
2     ...)
3 {
4     z <- object
5     p <- z$rank
6     if (p == 0) {
 >

So I'm not sure were you're getting your version.  What does 
`getAnywhere(summary.lm)' give you?
