R-developers,
The results below seem inconsistent. From the documentation for is.numeric, I
expect FALSE in both cases.

 x - data.frame(dt=Sys.Date())
 is.numeric(x$dt)
[1] FALSE
 sapply(x, is.numeric)
  dt
TRUE

## Yet, sapply seems aware of the Date class
 sapply(x, class)
  dt
Date

Thanks,
Robert

PS. Sorry if this sent twice. I originally sent this on Monday to
[EMAIL PROTECTED], but it didn't seem to go through. Perhaps it's a
deprecated  email address (?).
