pairs.data.frame(x, labels = names(x), panel = points, minlength = c(4,7), ...)
labels[1]
,
labels[2]
, etc., are the labels for the 1st, 2nd, etc., panel in the diagonal panels. If supplied, the label vector must have length equal to
ncol(x)
.
x
,
minlength
is passed to the argument of the same name in the
abbreviate
function, which is used to abbreviate the factor levels for unclustered labeling. See the documentation on
abbreviate
for more detail.
invert=FALSE
, the variable labels appear in the southwest to northeast diagonal panels. The default is
invert=TRUE
, which places labels in the northwest to southeast diagonal panels.
col
and
cex
) may also be supplied as arguments to this function. See the
par
help file for more details.
Currently,
pairs.data.frame
passes graphical parameters to both
plot
and
points
, so the parameters must be accepted by both functions.
This means, for example, that
xlim
and
ylim
are not accepted by
pairs.data.frame
, since they are high-level parameters that can only be given to
plot
.
x
.
This function is a method for the generic function for the class data.frame. It can be invoked by calling for an object x of the appropriate class, or directly by calling regardless of the class of the object.
