[R] summary.lm

[Marc R. Feldesman]

I ran across this error the other day while using lm().  I confess that I 
haven't used it for awhile and haven't been tracking the changes between 
versions of R.  However, the piece of code below is a tiny modification of 
the example in the help file for "lm".  I just separated the commands apart 
for clarity.  A similar piece comes from the help file for "summary.lm".

Aside from simply typing >lm.D90 at the command line, is there no longer a 
working summary method for lm.  I've looked at the code for summary.lm and 
its first two lines are:

z <- .Alias(object)
     Qr <- .Alias(object$qr)


 >lm.D90 <- lm(weight ~ group )
 > summary(lm.D90)
Error: '.Alias' is defunct.
See ?Defunct.

I'd be perfectly happy to be straightened out here.

Thanks.
