xyrange
returns a list with elements x
and
y
, vectors containing the minimum and maximum of
x- and y-values the argument(s). This
function serves to determine a plot region.

logical, indicating if all non-finite elements should be omitted. |
The default method passes the arguments x
and
y
to function xy.coords
. Therefore,
reasonable results can also be expected when e.g.
y
is NULL
and x
is a list or data
frame with components x
and y
.
If finite is TRUE
, the minimum and maximum of all
finite values is computed, and NA
and NaN
values are ignored.
A list with elements x
