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.

x,y |
numeric vectors of x- and y- coordinates, or alternatively a single
argument |
finite |
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
