range {base} | R Documentation |
range
returns a vector containing the minimum and maximum of
all the given arguments.
range(..., na.rm = FALSE) ## Default S3 method: range(..., na.rm = FALSE, finite = FALSE)
... |
any numeric objects. |
na.rm |
logical, indicating if NA 's should be
omitted. |
finite |
logical, indicating if all non-finite elements should be omitted. |
range
is a generic function: methods can be defined for it
directly or via the Summary
group generic.
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 NA
s) nonempty argument left, see min
.
