[R] Does this exist: diff(range(VAR, na.rm=T))

[Ebert,Timothy Aaron]

I do not see the problem.
In base R
Min <- min(var, na.rm=T)
Max <- max(var, na.rm=T)
Span <- c(Min, Max)

Is the same output as
Span <- range(var, na.rm=T)

diff(range(var, na.rm=T)) returns Max - Min

range() returns a vector with two values, the minimum and the maximum.
What should the function "span" do that is not already done?

I often need to determine the span of the x-variable in a graphic.

This is easy to determine with:
        diff(range(VAR, na.rm=T))

I am not aware of any function in base R that accomplishes this and "span" is not taken.

Would it be possible to add such a function?  Not a major addition but often useful.
