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 (?).
