[R] abs() on data frames?!

[Henrik Bengtsson]

I might be wrong, but didn't the following work before R v1.4.x?

R --vanilla
> df <- data.frame(-10:10)
> abs(df)
Error in abs(df) : non-numeric argument to function

I have tried this on both Rv1.4.1 on WinMe and Rv1.4.0 on Solaris 8. I
regexp searched bugs.r-project.org on "abs" but I found nothing about this.
I can't see why abs(df) shouldn't work when sqrt(df), log(df) etc works.

Thanks
