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


x <- data.frame(dt=3DSys.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,
