range returns a vector containing the minimum and maximum of
all the given arguments.

group generic. Methods for it must use the signature
x, ..., na.rm.range is a generic function: methods can be defined for it
directly or via the Summary group generic.
For this to work properly, the arguments ... should be
unnamed, and dispatch is on the first argument. If na.rm is FALSE, NA
and NaN values in any of the arguments will cause NA values
to be returned, otherwise NA values are ignored.
If finite is TRUE, the minimum
and maximum of all finite values is computed, i.e.,
finite = TRUE includes na.rm = TRUE.
A special situation occurs when there is no (after omission
of NAs) nonempty argument left, see min.
