range
returns a vector containing the minimum and maximum of
all the given arguments.
range(…, na.rm = FALSE)# S3 method for default
range(…, na.rm = FALSE, finite = FALSE)
any numeric
or character objects.
logical, indicating if NA
's should be
omitted.
logical, indicating if all non-finite elements should be omitted.
This is part of the S4 Summary
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 NA
s) nonempty argument left, see min
.
