plot.scores
is simply a wrapper calling scoreplot
,
passing all arguments. Similarly for plot.loadings
. scoreplot
makes one or more scatter plots of the scores,
depending on how many components are selected. If one or two
components are selected, and identify
is TRUE
, the
function identify
is used to interactively identify
points.
If scatter
is TRUE
, loadingplot
works exactly
like scoreplot
. Otherwise, it makes a lineplot of the selected
loading vectors, and if identify
is TRUE
,
uses identify
to interactively identify points.
scoreplot
and loadingplot
can also be called through the
plot method for mvr
objects, by specifying plottype
as
"scores" or "loadings". See plot.mvr
.
scoreplot
and loadingplot
also work with
princomp
objects. (However, plot(scores(...))
and
plot(loadings(...))
will not work.)
